Types of Mining Processing Plants

Mining processing plants are designed based on the type of mineral being processed and the recovery method employed. Understanding the different plant types helps in selecting the right configuration.

Crushing and Screening Plants

These plants reduce the size of mined ore without recovering any valuable mineral. They are used for:

• Aggregate production for construction
• Pre-concentration sizing
• Dimensional stone processing

Key Equipment: Jaw crushers, cone crushers, impact crushers, screens, conveyors

Concentration Plants

These plants separate valuable minerals from gangue based on physical or chemical properties:

Gravity Concentration Plants:

• Use density differences for separation
• Common for gold, tin, tungsten, iron ore

Flotation Plants:

• Use surface chemistry differences
• Standard for copper, lead, zinc, nickel sulfides

Types of Mining Processing Plants

Magnetic Separation Plants:

• Use magnetic properties for separation
• Common for iron ore, magnetite, some copper

Leaching Plants

These plants dissolve valuable metals in chemical solutions:

• Heap leaching: For low-grade ores, copper, gold
• Agitation leaching: For higher-grade ores, gold, copper
• In-situ leaching: Solution injected into ore body

DRI (Direct Reduced Iron) Plants

These process iron ore to produce metallic iron for steel-making, using reducing gases rather than traditional smelting.

WSHT provides equipment and EPC services for all major types of mining processing plants.
