Gold extraction and refinement

Gold extraction using gold sand is the physical properties of minerals, chemical treatments do not ore, alluvial gold does not change the nature of the original, so the purity is not high Shajin Ti refining. Because sand gold refining changes the purity of gold through fire and electrolysis.

The following is a separate introduction of gold extracted from gold and gold in sand gold! The gold extracted from gold is the physical property of minerals. It does not chemically treat the ore, and does not change the nature of the original gold. Therefore, there is no high purity in sand gold. Because sand gold refining changes the purity of gold through fire and electrolysis. The following is a separate introduction of gold extraction from Shajin and Shajin gold!

Gold extraction from sand gold: The ore needs to be crushed and ground and pre-concentrated by ore dressing or gold is separated 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 sand gold ore dressing equipment. The flotation method is a widely used ore dressing method for rock gold mines. About 100% of the rock gold mines use this method to select gold, sand gold ore dressing equipment, sand gold beneficiation equipment and equipment level have been greatly improved.

The method of extracting gold into gold: There are two main methods for extracting gold into gold. One is pyrometallurgy; the other is electrolytic gold extraction. Pyrometallurgical is the first to crush the ore, to be enriched by heavy sand method, enriched, and then refined in the furnace; electrolytic gold extraction is to use sodium cyanide solution to dissolve the gold in the ore, and then put the gold through the electrolysis method. With this refining method, the purity of gold can reach 99.9%.

Paper Machine headbox is the key of paper machine, it has three functions:

1. Spread the stock evenly along the width of the paper machine.
2.Accelerate the stock up to the machine operating speed.
3.Suspend the pulp fibers throughout the outgoing slurry.


 The headbox use the air-cushioned type so that the work speed can be faster than the open-type.The enclose wall of the air-cushioned headbox is polished by the stainless steel.It have the stainless steel holy roll and use the tapered pipe inlet and organic glass diffuser headbox pulp.
