Copper recovery by flotation - Springer LinkCopper recovery by flotation. Slag composition loses priority to controlled cooling of the slag. by K. N. Subramanian and N. J. Themelis. In recent years, some copper smelters have turned to the use of milling for recovering the copper content of converter type slags. The reasons for doing this have in- cluded the advent of.copper flotation from converter slags,Hydrophobic-surface of copper from converter slag in the flotation .The converter slag from a smeltery in Daye contains 2.01% copper. The floatability of copper has a significant influence on the flotation of converter slag. Flotation tests, contact angle tests and FTIR were conducted to assess the influences of pH and different flotation concentrators on its hydrophobic process, mechanism.

At the same time the excess sulfur in the ore reduces copper(II) sulfide, CuS, to copper (I) sulfide, Cu2S, which melts and flows out of the bottom of the furnace. The slag is less dense and floats on the top. The molten copper(I) sulfide, called copper matte, is run into a converter furnace, where air containing oxygen is blown.
