hydrometallurgical

This is the first large-scale use of a hydrometallurgical process.

Metal recovery is the final step in a hydrometallurgical process.

The processes used are of many types, including pyrometallurgical and hydrometallurgical techniques.

The town is the site for a hydrometallurgical plant; construction began on this plant in the spring of 2009.

Sometimes, hydrometallurgical processes may be carried out directly on the ore material without any pretreatment steps.

The hydrometallurgical process, and the lack of fresh water at the site requires the construction of a desalination plant.

The processing plant will initially be a small demonstration operation to test new hydrometallurgical technology for separating metal from ore.

Small scale testing has established that a hydrometallurgical process can effectively recover all four metals, with competitive economics.

Additionally, electrochemical phenomena play a considerable role in many mineral processing and hydrometallurgical processes.

The most common hydrometallurgical process is leaching, which involves dissolution of the valuable metals into the aqueous solution.

The hydrometallurgical process for laterite ore can use sulfuric acid or ammonia leach solutions.

Many mechanical plants also incorporate hydrometallurgical or pyrometallurgical processes as part of an extractive metallurgical operation.

It is also the location of a copper mine, smelter and hydrometallurgical plant that was operated by the state-owned Gécamines.

These pyrometallurgical or hydrometallurgical treatments are themselves usually followed by cyanidation and carbon adsorption techniques for final recovery of the gold.

In metallurgical processes tank leaching is a hydrometallurgical method of extracting valuable material (usually metals) from ore.

This reddish paramagnetic solid is an intermediate in the hydrometallurgical purification of cobalt from its ores.

The Winlo process was developed for the low-cost chemical conversion of relatively pure uranium concentrates to green salt by a hydrometallurgical process.

Another hydrometallurgical routes is the Caron process, which consists of roasting followed by ammonia leaching and precipitation as nickel carbonate.

Electrowinning is an electrolysis process used to recover metals in aqueous solution, usually as the result of an ore having undergone one or more hydrometallurgical processes.

The demonstration plant was an initial step toward the ultimate development of a commercial hydrometallurgical processing facility to be constructed and operated in Long Harbour, Newfoundland.

Industries such as food & beverage, hydrometallurgical, water softening, catalysis, bio-based chemical etc. use ion exchange as a critical step in processing.

Gold extraction or recovery from its ores may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.

Pyrohydrolysis of hydrochloric spent pickle liquor from carbon steel pickling lines is a hydrometallurgical reaction which takes place according to the following chemical formulae:

The basic carbonate is an intermediate in the hydrometallurgical purification of nickel from its ores and is used in electroplating of Ni.
