Starting with the leaching stage, an aqueous solution is used to dissolve gold from ores. Cyanide solutions are very efficient but their toxicity makes the development of alternative reagents such as thiosulfate (Birich et al., 2019; Sousa et al., 2016), halides, thiocyanide, thiourea and microbial leaching (Beckman and Thompson, …

The rare earths, or rare earth elements (REE), are a relatively abundant group of elements consisting of scandium, yttrium, and the 15 elements of the lanthanide series of the periodic table. Scandium (Sc) is the lightest rare earth element. Scandium is present in crustal rocks in amounts greater than lead and precious metals, but it rarely ...

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by …

What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

Salt/Halite Mining Process. Salt is generally produced one of three ways: deep-shaft mining, solution mining or solar evaporation. Deep-shaft mining is much like mining for any other mineral. Typically, the salt exists as deposits in ancient underground seabeds, which became buried through tectonic changes over thousands of years.

The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals.

Production of iodine from caliche ore is a two-step process: 1. Extraction of iodate solutions from the caliche ore. 2. Reduction of iodate to iodine. Iodate can be extracted from ore by leaching in one of two ways depending on the ore's nitrate concentration: •Heap leaching for low nitrate containing ores.

Biotechnology has the potential to transform uneconomic gold reserves into resources. Bioprocessing can be attractive for: 1) low grade gold ores that are too expensive to process using conventional processes and 2) ores that contain impurities that foul conventional processing equipment (e.g. arsenic in gold ore).
