New process of gold beneficiation equipment improves grade
The content of gold in the ore is extremely low. In order to extract gold, it is necessary to crush and grind the ore and pre-concentrate by ore separation or to separate the gold from the ore. The most used in gold beneficiation is re-election and flotation. The re-election method plays an important role in the production of gold. Flotation method is a widely used ore dressing method in rock gold mines. At present, about 80% of China's rock gold mines With this method of gold selection, the level of mineral processing technology and equipment has been greatly improved. The amalgamation process is an ancient gold extraction process that is both simple and economical and is suitable for the recovery of coarse-grained monomer gold. This method is still used in many gold mines in China. With the development of gold production and the advancement of science and technology, the gold extraction process of amalgamation has been continuously improved and improved. Due to the increasingly strict environmental protection requirements, some mines have eliminated the amalgamation operation and replaced them with gold extraction processes such as re-election, flotation and cyanidation. In the gold production, the amalgamation process still has an important role in the gold extraction process, and there are application examples at home and abroad. At present, many gold mines such as Zhangjiakou in Hebei, Erdaogou in Liaoning, Jiapigou in Jilin, and Weinan in Shandong have applied this technology. The Erdaogou gold deposit in Liaoning was originally a single flotation process. According to the ore property, the combined process of amalgamation and flotation was changed. The total recovery rate was increased by 7.81% (the recovery rate of amalgamation was 64.6%) and the grade of tailings was 0.74g/t. It dropped to 0.32g/t and the annual benefit was 1.58 million yuan. The key to the amalgamation process is how to take protective measures to eliminate mercury pollution. The gold beneficiation production line consists of the main equipment such as jaw crusher , ball mill , classifier, flotation machine, leaching adsorption tank, concentrator and dryer. It can be combined with the ore feeder, hoist and conveyor to form a complete beneficiation production line. The production line has the advantages of high efficiency, energy saving, high processing capacity and economical rationality. The production process of the ore dressing production line is as follows: the mined ore is firstly crushed by the jaw crusher, and after being crushed to a reasonable fineness, it is evenly sent to the ball mill through the hoist and the ore feeder, and the ore is crushed and ground by the ball mill. The ore fines ground by the ball mill enter the next process: classification. The spiral classifier cleans and classifies the ore mixture by the principle that the specific gravity of the solid particles is different and the rate of precipitation in the liquid is different. The washed and graded mineral mixture separates the magnetic material in the mixture by magnetic force and mechanical force when passing through the magnetic separator because of the different specific magnetic susceptibilities of the various minerals. The mineral particles that have been initially separated by the magnetic separator are sent to the flotation machine, and different drugs are added according to different mineral characteristics, so that the desired minerals are separated from other substances. After the desired minerals are separated, because they contain a large amount of water, they must be initially concentrated by a thickener and then dried by a dryer to obtain dried minerals.
