Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below: I. Physical Gold processing technology: Crushingamp;Grinding Gravity Separation Flotation Process Agglomeration II. Chemical Gold processing technology: Carbon in Leaching Carbon in Pulp
Gravity beneficiation is refers to separating gold ore according to mineral density and plays an important role in contemporary mineral processing methods. The main gravity separator equipment are chute, shaker table, mineral jig, hydrocyclones, etc. Gold flotation. Flotation process is widely used for lode gold processing.
Small miners employ this process due to alluvial deposits contain free gold, the process is fast and efficient, the final product has a high gold grade and recoveries are between 80 to 95%, commercialization is fast and simple without brokers, the process is simple and is not necessary a big investment or very special technical knowledge, the mercury can be reused and its losses are minimized, the final product weight is small and can be transported easily from the process plant to the ...
The first process of gold extraction is screening, because the presence of large gravel will affect the efficiency of gold washing and damage the washing equipment, and this gravel even does not contain gold at all, so the first process is to screen the gravel from the gold ore, usually screening the gold deposit with a simple and practical screen is a good choice.

After the initial screening, the influence of large gravel on the gold selection process has been removed. The second process is desludging and disintegration. Desludge and disintegration actually doing the same job, that is, by sand washing, mechanical scrubbing and other progress, the gold and mud in the mine are fully diluted to prevent the gold from being wrapped in the soil, this ways make the gold to be freed so that the gold can be recovered. There are many methods for de sludge and disintegration. The most common ways is washing, The mud with high mud content is usually washed by a cylinder washing machine or spiral washing machine. And the mud with low mud content is washed with trommel screenand then screening.
The third process is the sorting process. Gravity separation method is the most important and the only method for gold ore beneficiation. The common equipments used in the gravity separation method are chute , jig concentrator, shaker table, centrifuge, etc. Among them, only the chute and the jig concentrator are used for rough selection. The advantage of the rough selection is that the processing volume can be very large, but the disadvantage is that the recovery rate may not too high, while the jig concentrator can achieve a high recovery rate but the processing capacity is small and the process is more complicated than the chute. And the gravity separation equipment such as shaker table and centrifugal gold separator is mainly used for the selection of gold and gold ore mines. It is an equipment for selecting the coarse concentrate from the jig concentrator or chute.
The selection method of the gold deposit is mainly gravity separation and amalgamation. The gravity separation method is to further enrich and purify the coarse concentrate of the jig concentrator and the chute with a shaker table or a centrifuge, and the gold shaker table can obtain the final height. Purity gold powder, but the loss rate is high, the centrifuge enrichment is relatively large, but pure gold cannot be obtained. Therefore, many people in the gold selection process still use the amalgamation process, and the amalgamation method is not only simple and convenient but also has a high recovery rate. After the selection, the high grade gold powder can now be directly smelted into gold ingots. Thats all the entire process of gold dust washing and extracting.
Ultimate Guide for Gold Cyanidation Process. Cyanide method has a history of more than 200 years since it was used in extracting gold and silver in 1887. With the high recovery rate, strong ore adaptability, fast extracting speed, cyanide method is still one of the main gold extraction methods.
