Case Study: 2 TPH Hard Rock Gold Processing Plant in Colombia

JXSC Case Study: 2 TPH Hard Rock Gold Processing Plant in Colombia

 

1. Project Overview

This project is located in Colombia. The client is a local mining company, focusing on small-scale hard rock gold mining. They required a reliable and easy-to-operate gold processing solution.

 

2. Raw Ore Information

The raw ore is hard rock quartz gold with a maximum feed size of 150 mm. The gold particles are mainly fine gold, and need to be ground to 0-1mm size, to liberate the gold inside the rocks.

 

3. Processing Capacity Requirement

The client required a processing capacity of 2 tons per hour, with the possibility to upgrade to 5TPH or 7TPH in the future.

 

4. Our Process Design & Solution

Process Flowchart

Process Description:

1. The chute feeder smoothly feedsraw ore into the jaw crusher.
2. The jaw crusher crushes big rocks to medium size.
3. Hammer crusher is a secondary crusher for crushing medium-sized stones to a small size.
4. The ball mill is for grinding fine ore to very fine powder size below 100 microns, so that the gold concentratescan be released completely from rocks.
5. The centrifugal gold concentrator is used for the first step of gold separation from waste sands.
6. The shaking table is used for fine gold separation and upgrades the recovery rate.
7. The tailings from the gold centrifugal concentrator will go to the sluice box for recovering gold from tailings.
8. Finally, all gold concentrates will be sent to a gold smelting furnace for purification, so that customers can get pure gold bars.

Main Equipment List:

• Chute Feeder
• Jaw Crusher
• Hammer Crusher
• Ball Mill
• Centrifugal Gold Concentrator
• Shaking Table
• Sluice Box
• Belt conveyors
• Water Pumps & Slurry Pump & Diesel Generator & Control Panel

 

 5. Customer Questions & Our Answers

(1) Why do you use a ball mill instead of a hammer mill?

The ball mill is more suitable for fine gold recovery and provides better liberation for quartz gold. The output particle size of the hammer crusher is 0-2mm, while the ball mill processes material with a particle size of 0-1mm. 

(2) What gold recovery rate can be achieved?

The gravity recovery rate can reach 85–90%, depending on the ore condition. 

 

 

(3) Do you have a freight forwarder who can ship this equipment to the ports in Colombia? 

Yes, we have freight forwarders that we’ve been working with for many years. They can ship the equipment to ports in Colombia.

(4) We want to confirm tomorrow (Colombian time) whether the electrical components (control panel and cables) require special treatment, or if they should be removed from the quotation.

The equipment included in the quotation does not contain any magnetic or liquid components, and it is not subject to strict regulations. Furthermore, each main piece of equipment is equipped with an electric motor. Our products have been exported to many countries.

(5) Can you provide the equipment drawings?

Once we receive your deposit payment, our engineer will design the detailed plant layout drawing, foundation drawing for you,  and also each main machine’s drawing & machine operation manual.

All the technical support will be provided to assist with the installation.

(6) Do your products have CE or ISO certificates?

Yes, all the equipment in this order has CE certificates and ISO certificates.

 

 

(7) Could you tell me the approximate replacement cycle for the wear parts?

Yes, we can provide an estimated replacement cycle for wear parts.  

(8) We have a site for the installation of equipment. Can you design the plant layout based on the topography of our site?

Yes, we can design the layout of the plant based on your terrain.
