The configuration of gold ore dressing equipment should be based on different ore dressing process configurations. It is very important to choose a gold ore dressing equipment manufacturer with a wide range of equipment types and rich project experience. Xin Hai Mining Equipment insists on adopting an open-minded approach to each gold mine, customizing suitable processes and equipment to create ideal mining benefits! This article introduces different types of equipment from several aspects including gold ore flotation equipment, reselection equipment, cyanide equipment, and auxiliary equipment for gold ore dressing.
1. Gold ore flotation equipment
80% of China's rock gold ores are sorted using flotation processes. The main equipment used is flotation machines. Xin Hai Mining Equipment, as a manufacturer of flotation machine equipment, has successfully independently developed various models of flotation machines. Among them, the flotation machine unit of the KYF/XCF type flotation machine launched by Xin Hai has successfully solved the staggered configuration problem of KYF flotation machine. It not only saves the consumption of foam pumps, reduces equipment management and maintenance operations, but also greatly reduces investment costs, improves ore dressing efficiency, and achieves the effect of 1+1>2.
2. Gold ore reselection equipment
Gold ore reselection equipment is one of the commonly used equipment in gold selection process. It mainly utilizes the different settling speeds of materials with different densities in the medium to separate gold-bearing minerals. It is mostly used when there is a large difference in density between individual natural gold or gold and gangue minerals, which is effective and economical.
Reselection equipment is commonly used in placer gold ore dressing. Xin Hai placer gold ore dressing equipment mainly includes jig machines, shaking tables, and spiral chutes. The customized reselection process is more concise, less polluted, lower energy consumption, and lower cost, with a total production efficiency increase of 35% and a 20% reduction in investment costs.
3. Gold ore cyanide equipment
Gold ore cyanide equipment is the main equipment for cyanide leaching of gold. Its process has strong adaptability to gold ores containing natural adsorbents such as clay, graphite, oil shale, and iron oxide, as well as complex gold ores containing arsenopyrite.
The main processes of cyanide leaching for gold include cyanide leaching, adsorption from cyanide solution, and obtaining finished products. It can be roughly divided into two types: the conventional cyanide method for gold extraction process, which uses zinc powder displacement to continuously counter-current wash with thickeners, and the no-filter cyanide carbon pulp process, which does not require filtration and washing, and directly adsorbs and recovers gold from cyanide slurry using activated carbon. The process is complex, but the gold recovery rate is high, and the recovery rates of CIP and CIL can be stabilized at around 80%, or even more than 90%.
4. Auxiliary equipment for gold ore dressing
Auxiliary equipment for gold ore dressing mainly includes pre-selection equipment and dewatering equipment for gold ore. Pre-selection equipment for gold ore helps to provide suitable granularity and concentration of ore slurry for ore sorting operations, creating conditions for better gold recovery. Dewatering equipment for gold ore is used to filter and dewater the selected concentrates and tailings, so that the concentration of gold concentrate and tailings meets the standard requirements, and the moisture content of minerals is below 20%.
In terms of gold ore dressing, Xin Hai has rich project experience. Since its establishment in 1997, Xin Hai has nearly 30 years of history, and most of the projects undertaken during this period are related to gold mines. Here are a few classic cases for reference.
1. Shandong 1000t/d gold ore flotation project
The original ore grade of this project is 1.76g/t, and the final gold concentrate grade is 46g/t, with a high gold recovery rate of up to 92%. In addition, according to the nature of the gold ore and the characteristics of the designed process flow, Xin Hai Mining Equipment has adopted advanced equipment with low energy consumption, high efficiency, reliable operation, superior performance, and high mechanization degree for it, which is simple and reliable to operate and easy to maintain.
2. Mongolia 200t/a gold ore heap leaching project
The gold ore dressing project in Mongolia is a mining industry full industrial chain service project undertaken by Xin Hai Mining Equipment. At the same time, it requires the design of gold smelting construction engineering.
According to the experimental structure analysis, Xin Hai Mining Equipment has designed a gold ore heap leaching-adsorption-desorption-electrolysis-activated carbon acid washing and regeneration-smelting ore dressing and smelting process scheme for it. The equipment includes carbon adsorption columns, desorption electrolysis systems, acid washing agitation tanks, activated carbon regeneration furnaces, high-frequency gold smelting furnaces, etc.
3. Mexico 1200t/d gold ore cyanide project
This gold mine is flotation plant tailings. According to the engineering project contract signed by both parties, the design scope of this project mainly includes cyanide leaching system, reagent preparation system, desorption electrolysis system, smelting system, etc.
The original ore flotation tailings slurry is pumped to the pre-concentration machine, concentrated to a concentration of 40%, and then enters the cyanide leaching system for leaching and adsorption operations to obtain qualified loaded carbon. The qualified loaded carbon is then subjected to desorption electrolysis and smelting systems to obtain gold ingots.
1. Quality builds brands
Since its establishment, Xin Hai Machinery Design Institute has optimized and improved more than 80% of common dewatering equipment, won more than ten national patents, and strives for excellence to provide you with high-quality dewatering equipment.
2. Strength achieves success
For more than 20 years, Xin Hai has successfully won the recognition and praise of many well-known domestic and foreign enterprises with its excellent technology and service strength, and more than 500 whole mine service projects have been carried out in more than 90 countries and regions around the world.
