our flotation reagents are widely used for copper, lead, nickel polymetallic sulfide ore, non-sulfide ore and precious minerals like gold and silver, aiming to help miners improve their flotation process as well as raise useful minerals' recovery rate. up to now, we have served both at home and abroad, with products exported to many countries.
secondly, the presence of pyrite in copper ores requires the use of lime in such a way as to avoid the flotation of this iron sulfide mineral. previous studies show that calcium generates an effect that boosts the negative effect of clays in the flotation process of copper ores. this is an important difference compared to other applications.
a new reagent system, developed by versitech, inc., with assistance from doe's inventions and innovation program, recovers copper minerals at a much lower ph than conventional reagents and avoids floating pyrite. the process reduces or even eliminates both the lime used in copper flotation and the accompanying carbon dioxide.

flotation reagents for mineral processing. kemcore supplies various mineral processing reagents used in the flotation process. we supply reagent schemes which consist of collectors, depressants, activators, ph regulators, frothers. our flotation reagents are suitable for many metals, particularly copper, lead, zinc, silver, gold, and nickel.
this data on chemicals, and mixtures of chemicals, commonly known as reagents, is presented for the purpose of acquainting those interested in froth flotation with some of the more common reagents and their various uses.. flotation as a concentration process has been extensively used for a number of years. however, little is known of it as an exact science, although, various investigators have
the sequential copper lead zinc flotation practice utilizes several major reagent combinations in sequential copper lead flotation, which include: bisulfide method, starch/lime method and soda ash/so 2 or lime/so 2 method. the bulk copper lead flotation with depression of zinc followed by copper lead separation and re-flotation of
flotation reagents refers to the agent that used in mineral flotation process, which can adjust the flotation behavior of minerals thus achieving a good effect of mineral separation.currently using flotation reagents is the most flexible, effective, and convenient method of controlling flotation process.the commonly used flotation reagents can be mainly divided into three types according to
the recovery of these copper minerals by flotation or hydrometallurgy from ores, typically containing 0.5%tcu open pit mines and 1-2%tcu underground mines is of great commercial importance

the disadvantage of this reagent is: high reagent consumption, low ash flotation waste, high ash content of the concentrate, the high loss of coal due to the lack of selectivity of the flotation process. the objective of the invention is the improvement of process performance and efficiency of the flotation process of coal.
