2018/5/21Hydrometallurgical Processing of an Upgraded Apatite Concentrate In order to successfully recycle the mine tailings, all its components must be considered, not just the REEs. Since the primary mineral of the upgraded concentrate is apatite, which is one of the main resources of phosphorous, a process was developed that has its roots in H 3 PO 4 production. Get price

At last, leaching can be performed by solid waste addition to the filtrate (cell-free medium) including metabolites such as mineral or organic bio-acids [3, 7, 29]. Several comparative studies have been demonstrated in the case of these three approaches, and in most cases, the highest bioleaching performance was achieved in the spent-medium bioleaching approach.

4 Uranium Mining, Processing, and Reclamation

After the uranium ore is removed from the ground, it must be treated at a hydrometallurgical processing facility to remove impurities and produce yellow-cake. The specific type of hydrometallurgical process is also deposit-specific, dependent not only on the nature of the uranium mineral but also on the nature of the host rock as well as environmental, safety, and economic factors.

Innovations: How Hydrometallurgy and the SX/EW Process

To be applicable to this process, the ores must contain copper minerals in sulfide form; as mineral such as Chalcocite (Cu 2 S), Chalcopyrite (CuFeS 2) and Covellite (CuS) . In the concentrating operations these minerals are separated from the gangue material of the ore, that might contain as little as 0.5% copper to form a concentrate containing 27 to 36% copper.

A Clean and Efficient Method for Recovery of Vanadium

A cleaner method has been developed for the extraction of vanadium from vanadium slag. Compared to the traditional alkaline salts roasting followed by the water leaching process, in the nonsalt roasting process because no additives are added, the chromium spinel in the raw vanadium slag will not be converted to carcinogenic chromate salts and exhaust gas will not be produced.

Mineral_processing

Mineral processing, otherwise known as mineral dressing, is the practice of beneficiating valuable minerals from their ores. Industrial mineral treatment processes usually combine a number of unit operations in order to liberate and separate minerals by exploiting the differences in physical properties of the different minerals that make up an ore.
