Product Description

Product Description

 Gold Heap Leaching Process Plant

Introduction
The Gold Heap Leaching Process Plant is an efficient and cost-effective solution for extracting gold from low-grade ores. This method involves crushing the ore to a specific particle size, piling it on a prepared site, and leaching it with a cyanide solution through spraying or percolation.This process is widely used in the mining industry due to its simplicity, low operational costs, and flexibility in scale.

Key Features

• Simple Process: Involves basic steps of crushing, piling, and spraying, making it easy to operate.
• Low Energy Consumption: Requires minimal energy compared to other gold extraction methods.
• Flexible Scale: Suitable for small to large-scale operations, with capacities ranging from hundreds to thousands of tons per day.
• Cost-Effective: Reduces equipment and operational costs, making it ideal for low-grade ores.

General production process:
 

Crushing, Screening Process
The raw ore is fed into the primary crusher by a vibrating feeder, and then into the secondary crusher by a belt conveyor. The crushed ore is sent to the vibrating screen for sorting, the ore under the screen is sent to the powder silo, and the ore above the screen is sent to the third crusher by a belt conveyor for re-crushing. The crushed ore is then sent to the screening machine for sorting, which is a three-stage one-closed-loop crushing flow chart.
 

Grinding, Classification Process
The raw material from the powder silo is sent to the first ball mill through the feeder and belt conveyor. The ball mill discharges to the spiral classifier, and the slurry with larger particle size is returned for re-grinding. The overflow is pumped to the hydrocyclone for the second classifier, and the slurry with larger particle size enters the second ball mill, and the discharge returns to the second classifier. This is a two-step two-closed-loop grinding flow chart. The overflow of the hydrocyclone is sent to the slag screen and thickener.

Concentration
After dewatering and thickening by thickener, overflow pulp density of the classifier will be adjusted to the required concentration of the leaching reaction (40%), and to ensure uniform leaching process, continuous feeding.

Leaching And Adsorption
Concentrated pulp by thickener fed to the leaching tank by slurry pump, adding sodium cyanide stirred 20-24 hours. Gold with cyanide to form gold cyanide complexes, gold-cyanide complex is adsorpted by activated carbon, gold loaded carbon is formed, when carbon reaches a certain grade gold, with air lifter gold loaded carbon will mention to carbon lifting sieve to dewatering, and transported to desorption electrolysis systems by pump.

Desorption And Electrowinning
Desorption solution through heating delivered to the analytical column which loaded gold loader carbon, the desorption column will be temperatured, pressured, the gold precipitated from carbon. After desorbed, the bare carbon returned to the leach adsorption section. After desorption, the gold contained pregnant solution come into electrowinning cell, get gold powder, electrolysis lean solution can be returned for elution.

 

Product Parameters

Process Flow

1. Washing & Screening: Initial processing to remove impurities and prepare the ore for further separation. Vibrating screens and drum screens are commonly used for this purpose.
2. Crushing & Grinding: Reduces the ore to a fine size, typically 200 mesh, to ensure optimal separation during the gravity separation process.
3. Gravity Separation: Utilizes shaking tables and jig machines to separate gold particles based on their density.
4. Concentration: Further concentrates the gold particles to increase the overall gold content.
5. Drying or Smelting: The final concentrate can be dried or smelted to produce high-purity gold products.

Main Equipment

• Shaking Tables: Effective for separating fine gold particles. FTL Machinery's improved 6S shaking tables offer adjustable stroke lengths and smooth operation.
• Jig Machines: Utilize advanced variable frequency speed regulation technology for efficient separation of coarse gold particles.
• Centrifugal Concentrators: Ideal for recovering fine gold particles from placer gold, vein gold, and polymetallic ores.
• Spiral Chutes: Suitable for separating silica sand, zircon sand, titanium ore, and other mineral sands.
