Battery & Energy Minerals — A Fast-Growing Segment
The rapid growth of electric vehicles (EVs), battery storage and renewable energy is driving strong demand for lithium, cobalt, nickel, manganese, graphite, phosphate and other battery minerals. WSHT Mining Group designs mineral processing flowsheets for these critical minerals — covering both hard rock and brine-based deposits.
Our process engineering team combines comminution expertise with hydrometallurgical process design to deliver efficient energy mineral processing plants.
Lithium — Spodumene Hard Rock Processing
Hard rock lithium spodumene deposits are typically processed by crushing, grinding, dense-medium separation (DMS) and/or flotation to produce a spodumene concentrate, which is then further processed by roasting, leaching, purification and lithium carbonate / lithium hydroxide crystallization.
WSHT designs the crushing, grinding and physical beneficiation (DMS / flotation) front-end of spodumene processing plants — working in partnership with specialized hydrometallurgical technology providers for the downstream lithium chemical plant.
Lithium — Brine Processing
Lithium brine deposits (salt-lake / salar deposits) are processed by solar evaporation in ponds to progressively concentrate lithium, followed by impurity removal (lime / soda ash precipitation of magnesium, calcium, boron) and final lithium carbonate precipitation / crystallization.
WSHT provides crushing and screening plant design for the associated salt / mineral handling infrastructure for brine projects.
Cobalt & Nickel Processing
Cobalt and nickel deposits are processed by a combination of flotation (for sulphide ores), pyrometallurgical smelting (for high-grade sulphide concentrates), and hydrometallurgical leaching (pressure acid leaching, atmospheric leaching, bio-leaching) followed by solvent extraction and precipitation / electrowinning.
WSHT designs crushing, grinding and flotation circuits for cobalt and nickel sulphide ores — and partners with specialized technology providers for the hydrometallurgical refining stages.
Phosphate Beneficiation
Phosphate ore beneficiation typically includes crushing, grinding, scrubbing / desliming and flotation (anionic / cationic) to separate phosphate minerals from silica and other gangue. The resulting phosphate concentrate is used for phosphate fertilizer production and other industrial phosphate applications.
WSHT designs and delivers complete phosphate ore crushing, screening and beneficiation plants — including scrubbing, classification and flotation circuits.
