Abstract

"In this investigation it has been demonstrated that the Segregation Process has merit for treating oxidized lead ores.

The process comprises heating the crushed ore with salt and coal at about 750° C. to produce metallic lead attached to the carbon particles, which then is recovered by conventional flotation methods.

The quantities of sodium chloride and coal required for the best segregation of lead obtained in this work was 1.0 percent of coal and 1.0 percent of salt by weight.

Good segregation was obtained by using salt and coal as fine as 65 or 48 mesh. Segregation varied with the roasting temperature and time. At least 60 minutes was required for good segregation at 750° C.

About 3 to 4 percent moisture was required for segregation at 750° C.

Some valuable metals like silver, bismuth, precipitate along with the lead on the carbon particles. It is concluded that the process appears to have considerable merit on siliceous ores that are not amenable to conventional processing methods"--Abstract, page 2.
