Non-ferrous metallurgical processing

Non-ferrous metals play a vital role in modern industry, from energy storage and electronics to construction and transportation. Their processing requires precise chemical control to ensure high recovery rates and product purity across a wide range of ore types and extraction methods.

At Lhoist, we supply lime-based products used throughout non-ferrous metallurgical processes. Our solutions support the production of lithium compounds from brines and ores, enhance copper recovery through flotation and leaching, and optimize gold extraction across diverse ore types. Lime is also essential in refining bauxite into high-purity alumina and is widely used in other mining and extractive metallurgy applications.

Non-ferrous metallurgical processing sub-markets

Lithium

Lime is used during the processing of solution brines and mineral ores to produce lithium carbonate and lithium hydroxide.

Copper

Lime is used in the metallurgical processing of different copper ore types, ranging from flotation of copper sulphide minerals to leaching of copper oxides by acid lixiviants.

Gold

Gold is contained in many different ore types, each requiring a specific processing route for optimal gold recovery.

Alumina

Lime is used in various process steps during the refining process to convert bauxite ore into alumina (aluminium oxide) product in high purity powder form.

Others

Lime is used in a wide range of other applications from the mining and extractive metallurgy industries.
