Gold Ore Crushing Circuit Design for Heap Leaching 10mm

Designing a gold ore crushing circuit design for heap leaching 10mm requires balancing particle size, throughput, and capital cost. For heap leaching, a target product size of 80% passing 10mm is commonly used to expose gold particles to the cyanide solution without over‑grinding. Below we discuss the key stages of such a circuit and how OCP Mechanical Company helps you achieve efficient, cost‑effective crushing.

1. Key Stages in a 10mm Heap Leach Crushing Circuit

A typical gold ore crushing circuit design for heap leaching 10mm includes three main stages: primary jaw crushing, secondary cone crushing, and screening. The goal is to reduce run‑of‑mine ore (typically up to 500‑600 mm) to a final product where at least 80% is under 10 mm, while minimizing fines that can hinder percolation.

For a 100‑200 tph gold ore application, OCP recommends the Type H circuit configuration. Note: Product data are constantly updated; for the latest specifications of Type H, please contact our online customer service.

Primary crushing uses a jaw crusher (Type J) set at a closed side setting (CSS) of 100‑150 mm. The secondary stage uses a cone crusher (Type C) with a CSS of 10‑16 mm. A vibrating screen with 10 mm apertures returns oversize to the cone crusher, creating a closed loop. The above values are for illustration only. OCP continuously improves its products.

Many gold mines in West Africa and South America have adopted this gold ore crushing circuit design for heap leaching 10mm and report stable recovery rates with moderate wear costs.

2. How to Control Cost and Maintain Product Size

The success of any gold ore crushing circuit design for heap leaching 10mm depends on controlling three factors: feed consistency, crusher setting, and liner wear. Gold ore often contains quartz, which is highly abrasive, so wear part selection is critical.

To keep your circuit economical, we recommend:

• Using a variable speed feeder to maintain choke‑fed conditions in the cone crusher.

• Measuring CSS weekly with lead balls or a laser tool.

• Choosing manganese liners with 14‑18% Mn content for a good balance of toughness and wear life.

OCP’s Type C cone crusher features a hydraulic adjustment system that makes CSS changes quick and safe. Many operators find that with proper maintenance, a set of cone liners lasts 1,500‑2,500 hours when crushing gold ore to 10 mm. Actual wear life varies with ore hardness and operating practices – please ask our engineers for a site‑specific estimate.

As a direct‑selling manufacturer, OCP provides factory pricing on all wear parts and can ship to regional warehouses in Africa, Southeast Asia, and the Middle East within 15‑20 days.
