How to remove sulfur from the tailings after copper selection
Thread Content
The tailings remaining after copper selection contain large amounts of chemicals, which affect the sulfur removal efficiency. Those with experience in this area, please share!
It mainly depends on what type of ore it is; I’ve seen copper tailings being used to produce acid quite often.
Pass it through a spiral chute once – it’s simple and easy
The tailings from copper extraction are first have their pH value adjusted, then activated using copper sulfate; subsequently, desulfurization is carried out through flotation with xanthate. The sulfur obtained in this process can be used as sulfur concentrate for the production of sulfuric acid
The tailings contain 20% sulfur and 30% zinc, as well as small amounts of gold and silver. The plant does not have a roasting system nor an acid production system; what method should be used? The goal is to extract zinc and enrich gold and silver
