1992-05-05· The present invention involves a method for enhanced concentration of chalcopyrite from a low grade concentrate containing copper rimmed iron sulfide by use of a froth flotation process. The present process provides numerous advantages, including the ability to recover higher concentrations of chalcopyrite in a more efficient and effective manner than has previously been available.

This tells us that the concentrate has 9.57 times the copper concentration of the feed. 1.1.1 Grade/Recovery Curves While each of these single calculated values are useful for comparing flotation performance for different conditions, it is most useful to consider both the grade and the recovery simultaneously, using a "Grade/Recovery Curve".

During flotation three concentrates were collected at 3, 10 and 20 minutes of flotation time by scraping the froth into a collecting pan every 15 seconds. The head sample was taken for every test which was conducted. Head samples, concentrates and tails were filtered, dried

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

The result indicated that 37% of copper in the tails was recoverable by flotation. In this particular case we did not have kinetic rate data but instead recovery by size data.

Get PriceUsing these tools in combination with standard flotation tests can quickly and efficiently define the efficiency of a process and where potential improvements may be made. The following example shows the key aspects of using the theoretical grade-recovery curve for a copper flotation circuit where chalcopyrite is the major copper bearing mineral.
