Gold Tailing Disposal Technology

Gold tailing disposal is important in the mining processing, while gold tailing dam is the important part in mining processing plant. Traditional gold tailing dam is a great threat to resident nearby. There are some ways to prevent the threat from gold tailing.
Technology of high-effect dehydration -- pressure filtration of tailing. Usually, tailing is thickened to 50% to 60% through thickener and then transfer to tailing dam by diaphragm pump. Water in tailing dam is recovered according to permeation. Soil and water nearly are polluted during the permeation. Gold tailing could be filtering to over 90% and transferred by belt or truck to the dry tailing pile. We can reduce pollution according.
Tailings paste storage. Gold tailings will thicken in paste thickener, because paste thicker has higher underflow concentration than common thickener which will increase the degree of safety. Currently, paste storage has two kinds: full tailing filling and tailing pile. In full tailing filling,  tailings are thickened in paste thickener and then transported to fill mine. This way dealing with tailings could solve not only the tailing pollution but also the threat from mine. Tailing pile method is that underflow from paste thickener is transported to the tailing reservoir to pile.
Different gold tailings have different ways to deal with. Apart from the two way we discussed above, tailings could also be re-processed by flotation and re-used as materials to produce construction materials.
