9.1.3: Mineral Deposits, Ore Deposits, and Mining
Mining, the Environment, and Politics; A mineral deposit is a place in Earth's crust where geologic processes have concentrated one or more minerals at greater abundance than in the average crust. An ore deposit is a mineral deposit that can be produced to make a profit. Thus, all ore deposits are mineral deposits, but the reverse …

Ore Sorting Strategies In Mineral Processing
For successful mineral processing design it's critical to evaluate the possibility of preconcentration or waste diversion before grinding. Mess up this step and you could be hit with avoidable downstream CAPEX and OPEX costs. At its core, preconcentration means exploiting particle differences as early as possible so that waste material isn't …
Assessment of options for economic processing of preg-robbing gold ores

Mineral processing | Metallurgy, Crushing & Grinding
Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy.
Processing technologies for gold-telluride ores
Gold telluride ores are important gold refractory ores due to the presence of sulfides and other gangue materials. The classification and main physical properties of gold telluride ores were described, and possible treatment methods including flotation, leaching, and oxidation were reviewed. The results show that flotation procedures are …
Alternative Lixiviants to Cyanide for Leaching Gold Ores
Although some alternative reagents can give higher gold extractions with carbonaceous or refractory gold ores (Wan et al., 1995; Choi et al., 2013), cyanidation often achieves the highest overall gold recovery. For high-grade ores and concentrates, the economic benefit of increased gold recovery usually outweighs the reagent cost and …
