Generally speaking, pyrite is mainly recovered as by-product. Such as primary copper ore, lead-zinc ore, molybdenum ore and polymetallic ore, sulfur concentrate is mostly a by-product of recovery, commonly known as sulfur concentrate, sulfur concentrate and so on.
The mines recovered as the main products are generally chemical mines, the useful minerals are mainly pyrite, and the concentrates of other minerals may also be by-products.
Therefore, if your main product is sulfur concentrate, you should consider the equipment of the whole concentrator; If it is a by-product sulfur concentrate, only flotation equipment is needed.
In fact, pyrite is a very floatable mineral. If it is not a severely oxidized ore, the reagent system is also very simple, and generally only collectors and foaming agents are needed.
As for the equipment, there is no need to be demanding, and conventional flotation equipment can meet the requirements. Therefore, if it is not a large regular concentrator, there is no need to pursue too good equipment. Unless you have a lot of money.
Of course, if it is a concentrator that mainly produces sulfur concentrate, you need to fully consider the equipment status of the concentrator. Determining the equipment level according to the overall situation is not only a matter of concentrator equipment.
I wonder if you are satisfied with this answer?
