TYPICAL CONFIGURATIONS

Typical Plant Configurations

General examples only; the actual flowsheet depends on ore testing and site conditions.

Typical gold & silver configurations

Hard-rock CIL · placer gravity · gold-sludge refining equipment

  1. ①Crushing → grinding & classifying → gravity recovery of coarse gold
  2. ②Thickening → leaching & adsorption → desorption-electrolysis → gold-sludge refining

Typical copper configuration (500 t/d)

Three-stage crushing · single-stage closed grinding · 1 rougher, 2 scavengers, 2 cleaners

  1. ①Jaw + cone crushers + circular screen → grate ball mill + spiral classifier
  2. ②Two-stage conditioning → flotation → concentrate thickening & filtering, tailings thickening with water recycling

How a Shaking Table Works and How to Adjust It

A shaking table separates fine minerals by density using asymmetric reciprocating motion and a cross-flow of water. This guide explains how it works and how it is built, gives typical ranges for stroke, speed, deck slope, wash water, feed density and feed rate, and sets out a step-by-step adjustment method and a troubleshooting table.

Tin Ore Gravity Separation: The Flowsheet Explained

Cassiterite is heavy but brittle and easily overground, so tin is recovered mainly by gravity. This guide covers the typical flowsheet for alluvial and hard-rock tin: stage grinding, hydraulic classification, jigs, spirals, sized shaking-table circuits, slime treatment, and flotation and magnetic cleaning to remove sulfides and iron minerals.

FAQ

FAQ

What about lead time, payment and shipping?

These are stated clearly in every quotation.

Do you provide installation and after-sales support?

We provide process flow design, plant layout drawings, installation guidance and commissioning support.

I am not sure which equipment I need. What should I do?

Tell us the ore type, feed size, planned capacity and site water and power conditions. Our engineers will recommend a flowsheet and equipment configuration, with ore testing first where needed.

Can I buy a single machine?

Yes. We quote single machines, individual process sections or complete plants.

What information do you need for a quote?

Ore type and approximate grade, feed size, planned capacity (t/h), site water and power conditions, and the target product. The more complete the information, the more accurate the proposal.
