(1) Copper sulfide ore flotation

Copper sulfide ore is a copper ore with a meager oxidation rate. Almost all copper sulfide ores have iron-containing sulfides. In a sense, it is essentially the separation of copper sulfide and iron sulfide. When the content of iron sulfide minerals in copper ore is very high, the priority flotation process should be used; conversely, mixed copper and sulfur flotation and then separation should be given priority, but the priority flotation process is not excluded.

The process involves several basic steps, including crushing and grinding the ore to a fine size, then introducing chemicals such as collectors and frothers to create the right environment to separate the copper minerals from the priceless material. Air or nitrogen also helps create bubbles within the flotation cell to which copper sulfide particles attach and are subsequently recycled as concentrate.

Since the copper-sulfur raw ore grade has declined, the copper-sulfur recovery rate and the concentrate grade have increased to varying degrees. Using the JXSC copper sulfide ore flotation process, the copper concentrate grade is increased by 3.42%, the sulfur is increased by 2.95%, the copper recovery rate is increased by 2.88%, and the sulfur recovery rate is increased by 28.83%.
