Direct flotation of copper oxide ore

Copper exists mainly in the form of sulfide ore and oxidized ore in nature, the most important of which is sulfide ore, which is formed by the slow oxidative deterioration of sulfide ore. With the development of the defense industry, the electronics and electrical industries, and new technologies, the demand for copper is increasing, and although copper production is Get price

Flotation of Copper oxide ore

Because of the high flotation speed of oxidized ore after sulfidation, concentrate products are directly produced in the first 1-2 tank of the first roughing. Addition of reagents is of special significance to the flotation of copper oxide ores, especially sodium sulfide, which is not only an activator of copper oxide ores, but also an inhibitor of copper sulfide ores.Get price
