The flotation separation is a complex physical and chemical change process. Many elements affect the flotation separation process and its conclusion. Thus, it is very important to make it clear what elements may affect it.
The mineral processing industry belongs to the resource-type industry, which is also the traditional industry. With the revolution and modern mining industry advance, the industrial base of the mineral processing industry still exists. With the rapid development of the society, the demand of mineral is increasing. The development of the mineral separation technique directly affects the development prospect of the mineral processing industry. As a kind of main mineral separation method, the flotation separation has been concerned by more and more related experts. We make an analysis of the influential elements of the flotation separation process.
Each small change may have a great influence on the whole process and its result. Many elements may affect the flotation separation process. There are independent variables and subsidiary elements. In the flotation separation process, the independent elements include the mineral composition of ore, the permeation situation and hardness of some ore, the grades and proportion of ores, the content and composition of the dissolved ore, the oxidation situation of ore, and so on. The subsidiary elements are the ore grinding process and the classification process, including the machines, grinding media, lining plate type, pulp density, and so on, the oxidation situation of the ore in the grinding and flotation separation process, the flotation agent, the flotation separation time, and so on.
Above all, in the separation process, the subsidiary element is the precondition, which has been proved by experiments. The proper flotation conditions, obtained form experiments, should be kept without any changes of the independent elements, otherwise, the whole process will be damaged, which can not meet the industry separation index, including the recycling rate and the concentrate quality. On the contrary, with the changes of some independent elements, the subsidiary elements must be changed and there should be the according conditions for the flotation separation process.
