With the rising gold prices in recent years, it further stimulated the rapid development of gold industry. As the exhaustion of high-grade gold ore, researching on middle-low grade and refractory gold ore and strengthen the traditional gold mining process undoubtedly have become the main trend in global gold beneficiation industry.

Under the new situation, Yantai Group has paid long-term attention to gold recovery process, technology and equipment research & development. After 20 years of continuous studies, according to the different types of gold ore characteristics and user requirements, we have formed three gold beneficiation systems:

Cyanide Leaching Process Floatation Process Gravity Separation Process

Gold CIP Process: Fast Absorption Rates, High Recovery Rate

【Principle】The process that adopt activated carbon to adsorb and recovery gold from cyanide pulp directly without filtering carbon-in-pulp.

Leaching pulp preparation
Cyanide leaching→activated carbon adsorption
Gold charcoal desorption
Obtain gold mud through electric shock
Gold charcoal recycling
Leaching pulp process

【Products】 ◆ Leaching Agitation Tank ◆ Carbon Screen ◆ Washing Thickener ◆ Desorption Electrolysis System

【Advantages】Cancel the solid-liquid separation equipment, High gold recovery rate; Activated carbon counter current absorption, High adsorption rate

【Application】Flotation gold concentrate or amalgamation, gravitation separation tailings, or argillaceous oxidized gold ore

Gold CIL Process: Simple Process, Low Construction Investment, High Gold Grade

【Principle】The process that add activated carbon to the pulp and leach and adsorb gold simultaneously

Leaching pulp preparation
Leaching and absorption
Gold charcoal desorption
Obtain gold mud through electric shock
Gold charcoal recycling
Leaching pulp process

【Products】 ◆ Leaching Agitation Tank ◆ Washing Thickener ◆ Desorption Electrolysis System ◆ High Frequency Dewatering Screen

【Advantages】Simplify the leaching and adsorption process, Save construction cost; Fast gold dissolving speed, High recovery rate

【Application】Large gold processing plant, and the gold processing plant with much more associated silver and copper

Gold Flotation Process: Low Agent Consumption, Wide Application Range

【Principle】According to the difference of gold ore surface in chemical and physical properties, after the flotation reagents, the gold mine is attached to the bubbles selectively, achieving the separation

【Products】 ◆ SF Flotation Cell ◆ JJF Flotation, Wemco Flotation ◆ BF Flotation Cell ◆ XCF air inflation flotation cell ◆ KYF Air Inflation Flotation Cell

【Advantages】new flotation reagents, quickly collect gold-bearing sulfide concentrate, achieving efficient synthetically utilization; Low reagents consumption, high gold recovery rate

【Application】Vein gold deposit; gold-bearing sulfide ore

Gold Gravity Separation Process: Energy saving, Environmental Protection and Economical

【Principle】According to the relative mineral density difference to separate the gold mine

【Products】 ◆ Jig ◆ Shaking Table ◆ Spiral Chute

【Advantages】High efficiency, Energy saving, Environmental protection and economical; Simple process equipment, Low cost;

【Application】Gravel mine, often combines with other ore dressing process

Gold Heap Leaching Process: Less Construction Investment, Quick Production Result, Good Flexibility

【Principle】

Crush low grade gold ore
Store in leakproof foundation pad that paved by pitch, concrete or plastics
Spray low concentration of cyanide, alkaline solution, and non-toxic solvent or dilute sulphuric acid on gold stack to dissolve gold
Gold solutions penetrates from ore heap
Recovery the gold by activated carbon adsorption or the zinc powder exchange precipitation

【Products】 ◆ Jaw Crusher ◆ Spring Cone Crusher ◆ Heap Leaching System: spray and dripping leaching

【Advantages】Simplify the production process: efficient and fast gold dissolution; Small cover area; Good production flexibility

【Application】Often used to develop small ore body or low grade gold ore plants, or both, instead of the deposit that developed by conventional methods
