Broader terms: Recovery of scheelite and byproduct sphalerite from western U.S. tactite ores / (Washington, D.C.: U.S. Dept. of the Interior, Bureau of Mines, []). Low-grade titanium ores can be processed to form titanium slag or synthetic rutile using various processes to increase their primary TiO2 content in a secondary manner. Titanium slag can be utilized for pigment manufacturing using the sulfate process as well as the chloride process. As a byproduct, pig iron is always extracted in large quantities.5/5(1).

Additional Physical Format: Online version: Gomes, J.M. (John M.). Recovery of scheelite and byproduct sphalerite from western U.S. tactite ores. Bench-scale flotation tests were conducted on two western tactite ores to study the recovery of tungsten and zinc minerals.

The investigation, which is part of the Bureau of Mines ongoing program to develop methods for beneficiating minerals and metals from domestic low-grade ores, demonstrated the feasibility of producing scheelite, sphalerite, and their bulk concentrates.

Bench-scale flotation tests were conducted on two western tactite ores to study the recovery of W and Zn minerals. The investigation demonstrated the feasibility of producing scheelite, sphalerite. Thus, flotation was researched as a means for the selective recovery of scheelite.

An investigation was conducted by the U.S. Bureau of Mines to determine a procedure to efficiently float. Molybdenum is the primary, and often only, commodity in porphyry Mo deposits. Molybdenum mineralization occurs chiefly as molybdenite, and supergene enrichment is negligible, because molybdenite is relatively stable in the supergene environment (Plumlee, ).

Description: When found in nature, fluorspar is known by the mineral name fluorite. Fluorspar is calcium fluoride (CaF 2).Metallurgical grade fluorspar (60–85% CaF 2), is traditionally used as a flux to lower the melting point of raw materials in steel production to facilitate the removal of impurities, and in the production of c grade fluorspar (85–95% CaF 2) is used in the.

Many commodities that are commonly enriched in the gold-only deposits are defined as critical, energy critical, or near-critical in various reports on critical elements or rare metals that have been released over the past decade (e.g., National Institute of Advanced Industrial Science and Technology, ; National Research Council, ; European Commission, ; U.S.

Tellurium is distributed unevenly through the Earth’s crust. Hydrothermal and magmatic processes are the key mechanisms leading to high Te concentrations and the formation of primary Te minerals (Brugger et al., ).Tellurium is an essential element in over minerals, making it the most anomalously diverse element in mineralogy, i.e.
