Hydrometallurgy involves the separation of metals in a liquid phase by dissolving various metals from ores or concentrates in order to extract and valorise them. Nickel, uranium and copper are materials commonly processed using this technique.

Hydrometallurgy differs from pyrometallurgy, which separates metals based on different melting temperatures.

Hydrometallurgy consists of three main stages:

  • Leaching: Dissolving the ore in acid.
  • Purification: Electrochemical reduction or carburisation to remove impurities, especially heavy metals.
  • Selective metal separation.

The hydrometallurgy market

Minerals are primarily extracted from mines globally, necessitating widespread use of hydrometallurgy processes. Production sites, often in remote areas, operate continuously, generating increasing outputs.

Lixiviation occurs under specific pressure, temperature, and harsh conditions, requiring specialized industrial mixers for optimal performance.

LUMPP’s expertise in hydrometallurgical mixers

To meet the needs of the hydrometallurgical market, LUMPP offers:

  • Heavy duty mixers and rakes
