Product Description

The Content of Water-Soluble Flotation Reagent NaSH Is 70%


Product description:


Flotation Reagent is a process for the selective separation of hydrophobic materials from hydrophilic materials. It is mainly used in the mineral processing, paper recycling and wastewater treatment industries. Flotation agents can be used in conjunction with mechanical mining to economically recover valuable metals from much lower grade ore than before.

Flotation stage


1: Roughing

   The first stage is called roughing and produces a large amount of concentrate. It is to screen out the largest number of valuable minerals with the coarsest possible particle size. The finer the ore is, the greater the energy required, so only the particles that need to be finely ground are finely ground. Only sufficient enhancement of the flotation agent utilization rate can release enough ore from valuable minerals to achieve high recovery rates.

The main purpose of roughing is to recover as much valuable minerals as possible, while paying less attention to the quality of concentrate production.




The purpose of cleaning is to produce the highest possible concentrate grade.


Coarse beneficiation concentrates often require further grinding (commonly referred to as regrind) to more completely screen for more valuable minerals. Because it has less mass than the original ore, it requires less energy than regrinding the entire ore. Regrinds are often carried out in specialized regrinding plants (such as IsaMill), in order to reduce the grinding process and make it easier to find the required substances


3:Clean up

The rough flotation step is usually followed by a scavenger flotation step, which is applied to the roughing tailings. The goal is to recover any target minerals that were not recovered during the initial roughing phase. This can be achieved by changing the flotation conditions to be more stringent than the initial roughing, or some secondary grinding can be performed to further liberate.




1 : Flotation Reagent is the process of separating minerals from gangue using the differences in the hydrophobicity of the minerals. By using surfactants and wetting agents, the difference in hydrophobicity between valuable minerals and waste waste stones increases


2:This flotation method is also widely used in industrial wastewater treatment plants, where fats, oils, greases and suspended solids are removed from wastewater


3:Froth flotation is one of the methods used to recycle recycled paper. In the paper industry, this step is called deinking or flotation. The goal is to release and remove hydrophobic contaminants from recycled paper.



Due to the influence of the  season and the raw material market, the price of NaSH may fluctuate slightly!
