does cell phone production hurt all apes or just gorillas?
Columbite-tantalite (coltan) pit mining in the Democratic Republic of Congo can be highly profitable due to coltans use in portable electronic devices, but it is environmentally devastating, specifically for gorillas. This would not impact orangutans and gibbons directly as they are native to Asia, not Africa, but many species overlap in the DRC.
Here is a map of Africa that indicates the distribution of African apes. Chimpanzees have the largest distribution, and the apes with the smallest territory are mountain gorillas, cross river gorillas, and eastern lowland gorillas. Though Western lowland gorillas have the largest distribution of the gorillas, Coltan mining happens in their area as well as in the areas populated by more endangered gorilla species.
These mining practices are exploitative of every living thing that calls these areas home, including black and white colobus monkeys, drills, and humans who turn to mining either by working for the companies or selling/leasing their land to survive in the midst of devastating poverty. Coltan mining is a continuation of the resource exploitation that the Western world has inflicted on Africa throughout the entire history of its colonial occupation. Here is an interactive map of mines in Africa so you can see for yourself where they are and what minerals are extracted.
Coltan mining harms many species, but gorillas are the apes that are harmed the most and are at the greatest risk of extinction from it. Because this is the most pronounced threat to gorillas and because gorillas are such a large and attractive species, they have become the ambassador species for the cause. When you recycle your old electronics through a program such as the Calgary Zoo's Gorillas on the Line initiative you not only help gorillas, but everyone who shares the same home range as them.

Understanding Niobium Plate Manufacturing Process and Standards
Niobium plate is a highly malleable and easy-to-process metal with many applications in various fields of industry. It can be combined with other metals as an alloying base to form solid yet tough, high-strength low-alloy steels used for oil and gas pipelines, car/truck bodies, architectural specifications, tool steels or ship hulls.
Tumblr media
What Are Niobium Plates?
Niobium plates can be found in numerous manufacturing processes. When alloyed with other metals, niobium forms corrosion-resistant alloys that can be machined into any shape or size using traditional machining techniques.
They feature high electrical conductivity, making them perfect for welding applications while being resistant to stress and heat - making them suitable for high-temperature equipment components.
These properties, combined with its low capture cross section for thermal neutrons, make graphite an invaluable material in the nuclear industry. Furthermore, graphite can also be found widely used for superconducting magnets commonly seen in MRI scanners.
Metal oxides come in various forms, from rods and bars to sheets, foils and oxides ranging in thicknesses from 0.03mm up to 10mm.
Niobium Plate Properties
Niobium is a grey, crystalline metallic element with a high melting point and other desirable properties for manufacturers. Its primary application lies in metal alloy production; even small amounts (0.1%) can significantly enhance the strength, hardness, corrosion resistance and other properties of metals produced using it.
Niobium can be found naturally in columbite, euxenite and pyrochlore minerals; it can also be extracted from tantalum ores through mining operations in Canada and Brazil. Niobium has many high-tech uses making it an essential element in many high-tech products.
Nickel is one of three elemental superconductors with critical temperatures above the freezing point of water and is found in various magnetic materials and devices. It can be used to produce powerful magnets with very high fields; additionally, it's often included as part of medical imaging devices like MRI scanners; it is even popularly found as hypoallergenic jewellery components.
Niobium Plate Applications
Niobium is often employed for alloying steel, particularly high-strength low-alloy (HSLA) and stainless steel alloys. Due to its combination of strength, melting point and chemical corrosion resistance, it makes an ideal material for many applications in engineering industries worldwide.
Aerospace industries are another key user of high-purity niobium alloys. Jet engines, rocket engines and spacecraft components regularly feature hot alloys based on this metal due to their excellent thermal resistance and processability.
American Elements offers Niobium plates, sheets and rods in various thicknesses and sizes for multiple applications, including coatings, thin films and ALD, PVD and CVD deposition processes.
Niobium is an attractive metal for jewellery due to its low toxicity, ability to be anodized to create various shades, and versatility for medical devices, including superconducting magnets for MRI scanners.
Niobium Plate Standards
Niobium plate is typically produced through cold working processes, including forging, rolling, swaging, and drawing. Once created, this chemically pure metal can be used in applications like synthetic diamond production, sputtering targets production, fibre optic application etc.
Niobium is a highly malleable metal, taking an inordinately long time to work and harden. It cuts easily with a jeweller's saw and can be formed into desired forms via hand shaping, dapping, chasing or forging.
Cold working processes such as rolling, drawing and forging can reduce niobium cross-sectional area by up to 90% before further annealing.
Niobium is an ideal material for spin casting and can be cast using conventional tools such as wood formers or steel roller wheels with appropriate lubricants. Unfortunately, however, niobium does not perform well when heated in traditional die presses; hence it is more suitable for smaller-volume production runs.

432 TONNES OF RARE EARTH CONCENTRATES ARE EXPORTED BY AUXICO FROM THE DRC.
Toronto, Ontario / September, 2022 - The third and fourth trades by Auxico Resources Canada Inc. (CSE: AUAG) of a total of 432 tonnes of rare earth concentrates (monazite sands) from the Democratic Republic of the Congo ("DRC") were successfully completed, the company reports. Since April of this year, the Company has sold 720 tonnes of monazite, including the most recent trading transactions, with a total provisional value of US$ 3.8 Million. In accordance with the written sales agency contract ("SAA") between Auxico and Central America Nickel ("CAN"), Auxico will keep a commission of 15% of the sales price. The following highlights of the most recent DRC trade operations are provided for your review:
• The third and fourth trades' material was sold for a tentative total of US$ 2.1 Million. A total of US$ 1.1 million has already been paid, and the remaining amount will be paid after the item reaches its destination and the appropriate contractual paperwork have been delivered.
• Initial examination of material samples revealed an average grade of 14.01% neodymium and a composition of about 60% rare earth oxides (TREO). Within the following 10 days, SGS South Africa will evaluate samples of the material, and the findings are anticipated.
• In the upcoming quarter, the company wants to grow exports to 1,000 tonnes per month. This would represent a yearly sale value of almost US$ 72 million at the going rate of US$ 6,000 per tonne, with Auxico keeping a 15% fee.
• Several cooperatives in the DRC's North Kivu province are the source of the rare earth concentrations found in the non-radioactive monazite sands.
"We are extremely pleased to see the latest transactions of rare earth concentrates being finished, which further validates that the rare earth sale activities from the DRC are a sustainable source of revenue for the Company," said Frederick Kozak, CEO and President of Auxico. The project, which is located in monazite sands and is ready for direct shipping without previous concentration, has one of the highest TREO grades of any developing rare earth resource, making Auxico a market leader in the export of rare earths. By the end of 2022, the company hopes to sell 1,000 tonnes of monazite per month, and it works hard to make sure its operations in the DRC are fully traceable and ethically supplied.
In the Colombian region of Vichada, where the Company discovered high-grade concentrates with a total rare earth oxide content over 55%, Auxico has jurisdiction over a total of 1,482 hectares. The Company is working to get the necessary exploitation and environmental licences.
Furthermore, Auxico has a joint venture agreement for the Massangana tin tailings project in the Brazilian province of Rondônia. The Company plans to construct a 2,500 tonne per day processing facility there, which is expected to produce 13,500 tonnes of columbite, 6,000 tonnes of cassiterite, 90,000 tonnes of ilmenite, and 37,500 tonnes each of monazite and cassiterite per year. 300 million US dollars in annual income were expected in a recent economic prediction created by the independent Brazilian company PrimeStar under the Company's direction.
As a Qualified Person (QP) as defined by National Instrument 43-101, Joel Scodnick, P.Geo., an independent consultant to Auxico, reviewed and approved this news release.
Disclaimer: Because the Massangana production forecasts are based on conceptual models, the yearly prediction of tonnes for all of the aforementioned minerals does not meet NI 43-101 standards.
As it relates to Auxico Resources Canada Inc. The Canadian firm Auxico Resources Canada Inc. ("Auxico"), headquartered in Montreal, was established in 2014 and trades on the Canadian Stock Exchange (CSE) under the ticker AUAG. Auxico is involved in the purchase, exploration, and development of mineral properties in the Democratic Republic of the Congo, Colombia, Brazil, Mexico, and Bolivia. On the company's website (www.auxicoresources.com) or on SEDAR (www.sedar.com), under the heading "Auxico Resources Canada Inc.", you may find more information about Auxico.
ON BEHALF OF THE DIRECTORS' BOARD

HOW DOES A MAGNETIC SEPARATOR WORK?
Tumblr media
Based on the difference in magnetic characteristics of the ore minerals, magnetic separators are used to separate valuable minerals from non-magnetic gangue, such as magnetite from quartz, or magnetic impurities or other valuable minerals from non-magnetic values. Magnetic susceptibility is a characteristic of a magnetic separator that influences its response to a magnetic field. Materials can be classified into two groups based on their magnetic susceptibility: those that are attracted to a magnetic field are termed paramagnetic materials, and those that are repelled by a magnetic field are called diamagnetic materials.
Types of Magnetic Separator
Dry or wet magnetic separators are available. Permanent or Electro Magnet Magnetic Separator are two types of magnetic separators. Based on the relative magnetic field strength used to achieve separation, magnetic separators for the mineral processing sector are divided into three categories: low, medium, and high intensity. Magnetic separators include:
Wet high-intensity magnetic separators (WHIMS)
Wet / dry low-intensity magnetic drums (LIMS)
Induced roll magnetic separators (IRM)
Lift roll magnetic separators
Cross belt magnetic separators
Disc magnetic separators
Eddy Current Separator
Magnetic Separator Applications
Magnetic separators have been used to upgrade and beneficiate a wide range of minerals and commodities for a long time. There are three main applications for magnetic separators:
#1. Magnetic Separators for concentration or purification;
Magnetic Separators are used in ore processing to separate magnetic minerals, namely iron. For nearly 200 years, magnetic separation has been used in mineral processing.
#2. Magnetic separators for product cleaning;
Most common applications are listed as below:
Purification of Kaolin;
Removal of magnetic minerals from high quality quartz sand;
Separation ilmenite, monazite, zircon and garnet
Wolframite, cassiterite, tantalite, columbites concentration.
#3. Magnetic Separator for tramp iron removal;
Tramp iron separators safeguard handling and processing equipment such as screens, crushers, and pulverising machines, among other things. Magnetic pulleys on conveyor belts, plate magnets in chutes, grate magnets incorporated, and various magnetic drums fitted as independent components in separators are all examples of magnetic separators for tramp iron removal.
