200tph rock gold mining plant

A 200tph (tons per hour) rock gold mining plant is designed to process 200 tons of rock containing gold per hour to extract the precious metal. Such a plant typically includes several key components:

  1. Crushing Equipment: To break down large rocks into smaller pieces, which can be processed more easily.

    • Jaw Crusher
    • Cone Crusher

  2. Grinding Mill: To further reduce the size of the material to liberate gold particles.

    • Ball Mill
    • SAG Mill

  3. Gravity Separation Equipment: Often used to recover gold particles from the ore.

    • Spiral Classifier
    • Shaking Table
    • Centrifugal Concentrators

  4. Leaching and Adsorption: Use of chemicals to dissolve gold from the rock material.

    • Cyanidation Leaching Tanks
    • Carbon in Pulp (CIP) or Carbon in Leach (CIL) circuit

  5. Smelting: To produce doré bars (a semi-pure alloy of gold and silver).

    • Furnace

  6. Supporting Infrastructure: Conveyors, water supply, power, tailings disposal facilities, and more.

Key Points:

  • Capacity: 200 tons per hour.
  • Ore Type: Rock containing gold.
  • Processes: Crushing, grinding, gravity separation, leaching, adsorption, and smelting.

Major Considerations:

  • Site Layout: Design the plant layout considering material flow, worker safety, and operational efficiency.
  • Environmental Impact: Address environmental regulations regarding waste disposal and chemical usage.
  • Operational Costs: Consider ongoing costs, including energy, water, and personnel.
  • Recovery Rates: Aim to maximize gold recovery while minimizing losses.

Example Workflow:

  1. Feeding Section: Raw ore is fed into the jaw crusher.
  2. Primary Crushing: Larger rocks are crushed to smaller sizes.
  3. Secondary Crushing: Additional crushing to further reduce particle size.
  4. Grinding: Transfer crushed material to the ball mill.
  5. Gravity Separation: Initial gold recovery using centrifugal concentrators.
  6. Leaching: Ground material is subjected to cyanide solution.
  7. Adsorption: Cyanide gold solution passes through activated carbon in CIP/CIL process.
  8. Desorption and Electro-winning: Gold adsorbed on carbon surfaces is stripped and electro-winning produces solid gold.
  9. Smelting: Gold is heated to produce purer doré bars.

If you need detailed design or specifications, consulting with a mining engineer or process designer is recommended to tailor the plant to specific site conditions and ore characteristics.
