Gold Processing Plant

Gold Processing Plant

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, Xinhai Mining 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, Xinhai has formed three gold beneficiation systems:

Gold CIP Process Gold CIL Process Floatation Process Gravity Separation Process Cyanide Leaching Process

Xinhai Gold CIP Process: Fast Absorption Rates, High Recovery Rate

Xinhai gold CIP process

【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 ScreenWashing ThickenerDesorption 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

Xinhai 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 TankWashing ThickenerDesorption Electrolysis SystemHigh 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

Xinhai Gold Flotation Process: Low Agent Consumption, Wide Application Range

Xinhai gold flotation process

【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 CellJJF Flotation, Wemco FlotationBF Flotation CellXCF air inflation flotation cellKYF Air Inflation Flotation Cell

【Advantages】Xinhai 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

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

Xinhai gold gravity separation process

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

【Products】JigShaking TableSpiral Chute

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

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

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

Xinhai heap leaching of gold process


  • 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 CrusherSpring 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

Class B Design Qualification, 20 Years of Gold Processing Experiences

Xinhai has make Class B design Qualification, set up mine design institute and mineral processing research institute, more than 200 professionals provide the technical support service for gold processing plant, Since its establishment 20 years, Xinhai has been committed to gold processing service the development and innovation of equipment, and has formed the complete gold processing system. Xinhai concentrates on providing the Turnkey Solution for Mineral Processing Plant that is research and design- complete equipment manufacturing and procurement- commissioning and delivery”, striving for building the international leading enterprise in gold processing plant industry.

EU Certification International Quality

"Create a global brand, based on global gold markets " has been one of the strategic thought of Xinhai, depending on its professional gold processing service, Xinhai has got the EU certification, and ISO9001:2008 quality management system certification as early as in 2008, Xinhai is classified as the assured brand with advanced products and standard quality!
