the flotation investigation, for example, the sphalerite in the copper concentrate is mostly liberated. Therefore, use of mineralogy is one of the most important tools available to flotation investigators. The two critical questions that mineralogy helps answer are

Arsenic Content In The Lead Flotation

obtaining a lead concentrate with low content of arsenic. Ore sample, which was used in this flotation testing, contained a large amount of arsenopyrite over 40 by mass. The results showed that arsenic content in the rough lead concentrate can be decreased up to ten times compared to its content in the ore, using NaCN as depressant.

Froth Flotation Of Oilbearing Metal Sulfide Wastes
