nickel mining in australia – history, top locations and

Copper and nickel sulfide separation happen via crystallization, grinding and froth flotation. Copper and nickel sulfides are further refined. Laterite ores (saprolite) produce ferronickel used in steelmaking. Laterite ores (limonite and smectite) make melting-grade nickel. Processing of saprolite involves drying, calcination and smelting

process development essential to bentonite processing

Bentonite is a member of the smectite group of minerals and is primarily made up of montmorillonite. As a smectite, bentonite exhibits a combination of several important characteristics that have lent it to such widespread use. Key properties of the smectite group include:¹. 2:1 Expandable layers; High layer exchange; High base exchange capacity
