A copper mine in each divided into different components according to different pH, different pH, ore beneficiation process also changed, such as where the flotation stage, the flotation process is a main process ore sorting decision The level of concentrate grade. Therefore, depending on the acidity and alkalinity, the ore dressing methods used in copper ore beneficiation are also different.
Acidic copper ore cannot be directly discharged because it is rich in sulfur. According to experience, the ore flotation method of acid copper ore has the following methods: neutralization method, sulfide precipitation method, adsorption method, ion exchange. Law and artificial wetland law.
Copper Ore basic constituent elements is more and more, our Case Study in a copper mine, the mine sulfur-containing ore 30% or more, more than 1.2% copper, 1.3% or more zinc-containing alkaline solution neutral, if The direct acidification using the general flotation method cannot select the refined copper ore. The correct method is to use zinc and sulfur mixed to suppress the zinc, and the tailings and copper sulfate to activate the zinc-selecting process.
Therefore, it can be seen that different ore dressing methods (mainly flotation processes) are adopted according to different acid ore and specific composition of the ore, so that the concentrate grade of the copper ore can be greatly improved.
We have Dough cutting sending conveyor, Reciprocating Laminator, Three- roll sheeter, Recycle device, B/C/D Gauge Roller.
The laminator is the necessary equipment for soda biscuit production. The biscuit produced by laminator has the characteristics of distinct layers and crisp taste, which is conveyed to the molding machine to produce soda biscuit blank by clamping and laminating the dough after pressing.
