In the large tank percolation operation, the ore is crushed to -lcm, placed in a large tank with a slightly inclined bottom, filled with the leachate, soaked for a period of time, discharged the solution, and then filled, repeated several times until the copper is immersible Fully dissolved. The tank immersion is often a process in which a plurality of tanks are connected in series. In order to improve the permeability, the fine ore powder should be sieved first, otherwise the leachate will be uniformly passed through the ore block. Since the air is not sufficiently involved in the reaction, the leaching rate of the copper sulfide mineral in the tank immersion process is very low. The leaching tank of Chambishi in Zambia is 14m × 9m × 6m, 6 slots in series, 500t ore per tank. The sumping time is 8h, the leaching is 96h, the venting is used for 16h, and the leaching temperature is 20~35°C. The ore contains 1.9% copper oxide, 0.3% copper sulfide, and a total leaching rate of 74%. The sulfide ore is not leached. Every day, about 8 tons of copper is leached, and the consumption of acid is 30 kg.
Stirring tank leaching in the tailings leaching article has been mentioned in the application of a stirred tank, this method is suitable for fully ground fine ore fines (such as 90% ~ 75μm), the mixing tank is divided into mechanical stirring tank and air lifting mixing groove. In order to increase the rate of leaching of the oxidized ore, a higher initial and final acidity is required. Increasing the temperature helps speed up the leaching. However, the agitation tank has high investment in leaching and high running cost, and is mostly used for leaching of high-grade ore. The conditions for the sulphide ore leaching in the agitation tank are more severe, as described in the related article.
As we konw,most people like wear bracelet,because it can make a deifferent for people.Bracelet can be made of many material,common bracelet material is golden,silver ,stainlees and son on.But these material is stiff,rough and may cause skin irritation if worn incorrectly.Do we have a soft and smooth of texture,and that will not cause any allergic reactions after wearing?Of course! It is Siliocne bracelet.Silicone bracelet is made of 100% food grade siliocne,it is very safe for people and Eco-friendly for convironment.It is suitable for everyone,young,old,children,even baby!The range of people using silicone bracelets is wide,we think,Silicone bracelet must be hot sales in your market.

Large guns are used for leaching and leaching of high-grade oxidized ore (Cul%~2%). Earlier, this leaching method is used to produce high-concentration immersion liquid I, and then directly accumulate copper . The emergence of extraction methods has led to a decreasing use of tank immersion.
