3. MMA minerals, metals and use
Gold (Au): Used in high tech-equipment that includes satellites, medical scanners, televisions, computers, cell phones as well as jewelry.
Copper (Cu): Used for piping, circuitry, high-tech equipment, and much more.
Molybdenum (Mo): Used to make steel stronger, lighter, more rigid and less corrosive.
Palladium (Pd): Catalytic converters, electronics, dentistry, medicine, hydrogen purification, chemical application and ground water treatment.
Platinum (Pt): Catalytic converters and fine jewelry.
Nickel (Ni) Particularly useful for alloys it forms particularly with steel for stainless steel, catalyst for hydrogenation and is an essential nutrient for microorganisms and plants.
Cobalt (Co:) Used in the preparation of magnetic, wear-resistant and high-strength alloys. Colbalt gives a distinctive deep blue color to glass, ceramics, inks, paints and varnishes. It is also used as a radioactive tracer in the production of gamma rays. It is found in vitamin B12 and in organic forms is an active nutrient for bacteria, algae and fungi.
Rhodium (Rh): Used in catalytic converters, corrosive resistant coating, sterling silver and nuclear reactors.
Zinc (Zn): Makes many useful alloys including brass, used for galvanization, zinc oxide used for protective coating.
Elemental Lead (PB) lead-acid storage batteries, ammunition, glass, casting metals, sheet metals etc…
Lime: Used in environmental, metallurgy, construction, chemical/industrial applications.
Talc: Used in many industries such as paper making, plastic, paint and coatings, rubber, food, electric cable, pharmaceuticals, cosmetics, ceramics,
Garnet: Gemstones and abrasives.
Tungsten: Tungsten’s many alloys have numerous applications: incandescent light bulb filaments, x-ray tubes, electrodes in TIG welding, compounds in tungsten used industrially as a catalysts
4. Mining Taxes at work
Mining operations in which metal or gems are extracted are subject to a license tax, which is based on the gross value of the product. The value to which the tax rate is applied is the monetary payment the mining company receives from the metal trader, smelter, roaster or refinery. Revenue collected is deposited in the General Fund (58%), Abandoned Mines Account (8.5 %), Reclamation and Development Grants Account (7 %), Hard Rock Mining Impact Trust Account (2.5%) and to counties identified as experiencing fiscal and economic impact (24%). Of that 24% 37.5% allocation to a County Trust Account and the remaining 62.5 % is allocated to County and School Districts.
In addition the mining community pays property, payroll and net proceeds taxes.
5. What steps does mining take to protect the environment?
Montana mining is subject to all Federal and State Environmental Laws and Regulations effecting hardrock mining. Before any ground is disturbed mining companies must ensure, by way of adequate bonding, complete reclamation and remediation of exploration and mining sites. In addition update bonding requirements are ensured throughout the life of the mine.
