extracting metals from minerals pyrometallurgy

Jaw crushers usually do not work independently, but together with cone crushers, impact crushers, sand making machines, vibrating screens, etc., constitute a complete set of sand and gravel processing systems to achieve accurate processing of ore and rock and improve product pertinence , Increase its market value. Common production lines are: stone production line and sand production line.

Stone production line

On the basis of the stone production line, sand making machine equipment for fine crushing and shaping is added, which can realize the simultaneous production of machine-made sand and crushed stone. The entire production line is flexible in construction and diverse in output, which can meet the various processing requirements of customers. , To achieve the purpose of "one line with multiple uses", it is an ideal production line choice for producing highway surface materials, high-speed railway sand and gravel aggregates, hydropower station sand and gravel materials, port terminals and airport runways.

Pyrometallurgy - an overview ScienceDirect Topics

The extraction methods are typically based on pyrometallurgy, hydrometallurgy, and electrometallurgy principles that yield different products bearing nickel and cobalt. Pyrometallurgy produces a sulfur-deficient matte that can be further processed using leaching, solvent extraction, and electrowinning. High-purity nickel is produced after electrorefining or the vapometallurgy-based carbonyl process. Nickel

Introduction to Mineral Processing - Sepro Mineral Systems

Ore is a term used to describe an aggregate of minerals from which a valuable constituent, especially a metal, can be profitably mined and extracted. Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing, to liberate and concentrate those valuable minerals.

Pyrometallurgy - an overview ScienceDirect Topics

Most metals found in the Earth's crust occur as metal oxides and sulfides. These ores are usually treated by pyrometallurgical or by hydrometallurgical processes to recover pure metal. Pyrometallurgy can be defined as the treatment of ores at high temperature to effect their conversion to raw metals, or intermediate compounds for additional refining. In contrast, hydrometallurgy requires treatment with aqueous solutions to recover metals from their ores.
