The effect of mineral processing reagents on the pollution of the ecological environment is very complicated.There are direct harms and indirect harms.Next,let's take a look at how to deal with the industrial wastewater produced by the beneficiation reagent.
The purpose of rational addition of beneficiation agents is to ensure greater efficiency of the agents in the slurry and maintain an appropriate concentration.Therefore,according to the characteristics of the ore,the nature of the agent and the process requirements,the site and method of dosing can be selected reasonably.In addition,there are some situations that need to be added in batches.
Foaming agent is a type of surfactant that can reduce the surface tension of water to form foam,so that air bubbles in the aerated flotation slurry can be attached to the selectively floating mineral particles.Everything is good or bad.What aspects should be looked at to identify the quality of foaming agent?For specific methods,see what the beneficiation reagent manufacturer says:
The collectors become hydrophobic on the surface of the minerals and make the floating mineral particles adhere to the bubbles.There are many types and properties of the flotation agent during use.The following briefly introduces several collectors and properties.
Molecular adsorption,that is,the agent is adsorbed on the surface of minerals in the form of molecules.Such as the adsorption of neutral oil on the surface of non-polar minerals(graphite,molybdenite,etc.),the adsorption of double xanthate on the surface of sulfide minerals,and the adsorption of certain foaming agents(such as terpineol oil,fatty alcohol,etc.)on the gas-liquid Adsorption of the interface.
Xanthate is the most commonly used collector for flotation of sulfide minerals such as galena,yellow actinium,sphalerite,pyrite,natural gold,natural silver,mercury,and malachite.There are ethyl xanthate,pentyl xanthate and so on.Xanthates with 4 carbon atoms in the hydrocarbon group are collectively called low-grade xanthates,and xanthates with carbon atoms above 4 are collectively called high-grade xanthates.
In nature,except for coal,graphite,sulfur,talc and molybdenite and other mineral particles that have hydrophobic surface and natural floatability,most minerals are hydrophilic,and so are gold minerals.Adding a chemical can change the hydrophilicity of mineral particles and produce hydrophobicity to make them floatable.This chemical is usually called a collector.Collectors are usually polar collectors and non-polar collectors.
Molybdenum is a metal element that is rarely distributed in nature.There are about 30 molybdenum-containing minerals discovered today.The top three minerals are sulfide minerals,oxide minerals,and molybdate minerals.Among them,sulfide minerals are the representative.Molybdenite is the most widely distributed.At present,the metal molybdenum obtained from molybdenite accounts for more than 98%of the world's total molybdenum output.
