The process of separating gold with spiral concentrator is the process of separating gold using equipment by utilizing gravity system for obtaining gold ore. Spiral concentrator is one of the most effective ways and low cost in the mining industry which is used in the separation of mineral ore. One of the benefits of a spiral concentrator devices have no moving parts. The separation process mineral ore concentrates in gold mining in general should be done gradually, and a function of the mineral separation process to separate gold ore from dirt mineral or bearer minerals
The separation process mineral ore concentrate at gold mine in general should be done gradually, and the density of a material object, to obtain gold ore mineral. With the feed material is poured into a spiral concentrators ranges from 20% solids to 40% solids and has a size of materials such as flour sand (10 mesh to 200 mesh (2 mm to 0.075 mm) but depending on the material characteristics, maximum efficiency is usually in this range.
In the process of spiral concentrator for the separation of gold, by using heavy mineral concentrates which selectively directed into the spiral trough near with the inside of the spiral surface through the use of the splitter product. Then the mineral concentrate will flow through a circuit spiral from the top toward the bottom. When the material became into a dilute slurry mixture due to water flow, lightweight mineral materials which is easier to be carried away by the water going down with achieve high speed toward the bottom, and the heavier materials will be pulled into the inner edge of the spiral by water, which then separates the pollutant material and mineral ores.
In the separation of mineral ore concentrate has a variety of methods and the means used to obtain gold ore, such as the separation of gold by using chemical reagents, gold separation process in a simple way, or using means of modern equipment. Mineral separation process gold ore by using a chemical reaction can use several methods such as gold cyanide processing system, gold processing with Froth flotation system, gold processing by amalgamation, and processing of gold with other systems. For the processing of gold in a simple way can use panning, sluice box, dregging, gold separation process with spiral concentrator or other equipment. How simple processing can be done for mineral high-grade gold ore, or that generally have a size of mineral ore in the form of granules which can be seen with the naked eye.
Below is a video of a spiral concentrator process for separating gold. Video of the spiral concentrator describe how to the process of separating the gold material of impurities using a spiral concentrator equipment wich demonstration by product Alicoco
