Process for recovering metals from refractory ores

Feb 08, 1990· The following example demonstrates gold extraction from a refractory ore which only yielded 3540% extraction during cyanide leaching. Twenty grams of refractory gold concentrate containing 94% pyrite and 6% siliceous gangue were mixed with 100 g of solid salt (NaCl) to form an ore/salt mixture. The gold content of the concentrate was 8.91 g/t.

Zinc oxide ZnO PubChem

Two processes are used to produce metallic zinc from the ore concentrates that are not subjected to caustic soda leaching. In one process, the ore concentrate containing zinc sulfide is roasted in the presence of air to produce zinc oxide, which is combined with coke or coal and retorted to approximately 1,100 °C to produce metallic zinc.

Extraction of Resources Geology

Mining is the extraction of valuable minerals or other geological materials from the earth from an orebody, lode, vein, seam, or reef, which forms the mineralized package of economic interest to the miner.. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, dimension stone, rock salt, potash, gravel, and clay. Mining is required to obtain any material that cannot

Notes OCCURRENCE AND EXTRACTION OF METALS

16.2.2 Concentration or Dressing of the Ore Generally, the ores are found mixed with earthy impurities like sand, clay, lime stone etc. These unwanted impurities in the ore are called gangue or matrix. The process of removal of gangue from powdered ore is called concentration or ore dressing. There are several methods for concentrating the ores.

GEOPHYSICAL METHODS IN EXPLORATION AND

In the following discussion, the applicability of geophysical methods to geoenvironmental studies of ore deposits is reviewed. Details of geophysical techniques are not emphasized; these are covered in standard texts (Society of Exploration Geophysicists, 1966; 1990) and have been summarized in Hoover and others (1992).
