When flotating nickel ore, it is usually necessary to use a variety of chemicals to adjust the physical and chemical properties of flotation materials and flotation cutoffs to expand the hydrophobic-hydrophilicity (i.e. flotation) difference between flotation materials, thereby improving flotation. efficiency.
Here are some commonly used types of agents:
1. Nickel sulfide ore collectors: Commonly used collectors include xanthate, black drug, thiourethane, etc. Among them, the commonly used xanthate types include ethyl xanthate, butyl xanthate, amyl xanthate, Y89, etc., and the commonly used black drug type is butyl ammonium black drug.
2. Silicate mineral inhibitors: Commonly used inhibitors include polymeric phosphates, sodium carboxymethyl cellulose, water glass, soybean gum, starch, etc.
In addition, in practical applications, it is necessary to select appropriate chemicals and dosage according to the properties of the ore and flotation conditions. At the same time, the order and method of using reagents will also have an impact on the flotation effect, which requires reasonable adjustment and optimization. It is recommended to conduct sufficient testing and research before flotation to determine the best combination of chemicals and usage plan.
When flotating nickel ore, the addition and stirring of chemicals need to be adjusted according to the specific flotation equipment and process flow.
Generally speaking, the process of adding and stirring chemicals is as follows:
Add water to the ground nickel ore powder, stir evenly, and transport it to the flotation machine.
According to the properties of nickel ore and flotation requirements, select appropriate flotation agents and add them to the flotation machine.
After the agent and nickel ore have fully reacted, stir so that the agent is evenly distributed in the slurry.
According to the type of flotation machine and process requirements, adjust the stirring speed and time to achieve the best flotation effect.
It should be noted that the addition and stirring process of reagents need to be strictly controlled to ensure flotation effect and product quality. At the same time, the dosage and type of reagents also need to be optimized according to the properties of nickel ore and flotation requirements to achieve the best flotation effect and economic benefits.
