Mineral processing reagents only add reasonable, to ensure maximum efficiency and optimum dimensions, so according to the characteristics of the ore, the medicinal properties and technological requirements, reasonably choosing dosing dosing method and locations.
Dosing location choice is associated with the use and solubility of the drug, usually dispatch medium agent is added to the grinding machine, so that it can eliminate the activation or inhibition of the "inevitable" ion of the harmful effects of flotation, inhibitors should be added before the collector, is usually added to the grinding machine, the activator often join harmonic mixing tank, and pulp and a certain amount of time in the tank. Collecting agent and foaming agent is added to mediate in the tank and tank or flotation machine, and refractory collector (such as cresol black powder, baiyao, coal, oil, etc.), in order to promote its dissolved and dispersed, longer time and the effect of mineral, also often add to the grinding machine.
(2) were inhibition of mineral flotation, activator, collecting agent, foaming agent.
In addition, the choice of the dosing spot ore properties and other specific conditions must also be considered. Some copper sulfide - iron ore, for example, xanthate flotation plant to the grinding machine, the result can improve the copper indicators, in addition, the grinding cycle of single tank flotation machine installation to recycling solution from coarse particles, in order to increase the duration of the collector, also need the agent to the grinding machine
