If the gangue mineral in an iron ore is predominantly quartz, reverse flotation is usually used in the cleaning stage to improve the concentrate grade. Figure 9.13 presents a typical flow sheet for processing an oxidized iron ore containing about 30% Fe using a combination of SLon magnetite separators and reverse flotation. The ore is mainly composed of magnetite, hematite, martite, and quartz.get price

Bench-scale flotation of chrysocolla with n-octanohydroxamate

Increased residence time of the collector in the pulp prior to flotation substantially degraded the recovery and lowered the grades collected.

The iron was collected at recoveries of up to 70%, at grades of less than 7%.get price

Copper extraction Wikipedia

Most copper ores contain only a small percentage of copper metal bound up within valuable ore minerals, with the remainder of the ore being unwanted rock or gangue minerals, typically silicate minerals or oxide minerals for which there is often no value. In some cases, tailings have been retreated to recover lost value as the technology for recovering copper has improved.get price
