Selection of Mica Flotation Reagent

The selection and process of mica flotation agents have a crucial impact on the gold extraction effect. The following are some commonly used mica flotation reagents and their selection and process parameters:

Choose potion

Collector: Commonly used collectors include benzene, sodium sulfate, tartaric acid, stearic acid, etc. According to the precipitation form of gold and the mechanism of action of the agent, different collectors can be selected for use in combination.

Foaming agent: Commonly used foaming agents include oleic acid, abietic acid, stearic acid, etc. The function of the foaming agent is to generate a large number of air bubbles to entrain the entrained minerals to float up.

Inhibitors: Commonly used inhibitors are sodium hydroxide, sodium carbonate, etc. The role of inhibitors is to reduce the active sites on the surface of minerals, making it easier for minerals that are difficult to settle to float up.

Regulator: Commonly used regulators include oxidants, ammonia, etc. The role of the regulator is to adjust the pH, temperature and other properties of the medicament to improve the selectivity and gold extraction efficiency of the medicament.

Process parameters

Drug concentration: Drug concentration is an important parameter affecting the effect of drugs. Generally speaking, the higher the concentration of the agent, the higher the selectivity and gold extraction efficiency, but at the same time the cost of the agent will also increase.

Dosage of medicine: Dosage of medicine is an important parameter affecting the efficiency of medicine. Generally speaking, the greater the dosage of the agent, the higher the selectivity and gold extraction efficiency, but at the same time the cost of the dosage of the agent will also increase.

Heap thickness and speed: Heap thickness and speed are also important parameters affecting the effect of the agent. If the pile thickness is too large or the speed is too fast, the gas-liquid two-phase filling of the agent will be uneven, which will affect the gold extraction efficiency.

Gold extraction time and current density: Gold extraction time and current density are also important parameters that affect the efficiency of gold extraction. If the gold extraction time is too short or the current density is too high, the utilization rate of the agent will be reduced, thereby affecting the gold extraction efficiency.

In general, the choice of reagents and process parameters needs to be optimized and adjusted according to the actual situation to ensure the best gold extraction effect. At the same time, it is also necessary to pay attention to issues such as environmental protection and sustainable development in order to achieve a win-win situation of economic and social benefits.
