Our base-metal process-plant references include mineral-processing, smelting and refining applications and date back at least 25 years. We have experience in the following unit processes:

• Ore handling and preparation

• Comminution - Crushing, rod and ball milling, autogenous and semi-autogenous milling

• Classification - Hydrocyclones and screens

• Preconcentration - Dense-media and gravity separation

• Flotation - Flash, conventional, tank and column cells

• Dewatering - Conventional and high-rate thickeners, vacuum and pressure filters and driers

• Bulk materials handling - Belt-, chain- and pneumatic-conveying systems

• Sulphide oxidation - Roasting, microwaves and bacterial leaching

• Smelting - Submerged-arc, DC-arc and fuelled furnaces

• Converting - Peirce-Smith, top-blown and submerged-lance vessels

• Dust and gas collection - Bag filters, scrubbers and electrostatic precipitators

• Matte handling - Granulation and atomisation

• Leaching - Atmospheric, moderate and high pressure

• Solvent extraction - Copper, cobalt and nickel removal using BATEMAN pulsed columns and reverse-flow settlers

• Electrowinning - Copper, cobalt, nickel and zinc

• Other base-metal purification processes - Precipitation, cementation, ion exchange, MRT and crystallization Flexible contract structuring accommodates projects large and small, e.g. reimbursable, EPCM, lump-sum, fixed fee or joint ventures. BATEMAN also has finance-facilitation capabilities.
