Sphalerite ore proscessing plant - blende ore beneficiation methods for Nigeria

Sphalerite ((Zn,Fe)S) is a mineral that is the chief ore of zinc. It consists largely of zinc sulfide in crystalline form but almost always contains variable iron. When iron content is high it is an opaque black variety, marmatite. It is usually found in association with galena, pyrite, and other sulfides along with calcite, dolomite, and fluorite. Miners have also been known to refer to sphalerite as zinc blende, black-jack, and ruby jack.

The mineral crystallizes in the cubic crystal system. In the crystal structure, zinc and sulfur atoms are tetrahedrally coordinated. The structure is closely related to the structure of diamond. The hexagonal analog is known as the wurtzite structure. The lattice constant for zinc sulfide in the zinc blende crystal structure is 0.541 nm,calculated from geometry and ionic radii of 0.074 nm (zinc) and 0.184 nm (sulfide). It forms ABCABC layers.
Sphalerite ore proscessing plant
Sphalerite ore beneficiation methods:
1. flotation process: common sphalerite ore beneficiation main method;
2. flotation - magnetic separation method;
3. microbial induced flotation process: ore dressing technology and new ideas;
 
Sphalerite ore proscessing plant:
In the sphalerite processing process, it can be divided into three stages: crushing stage, grinding stage and beneficiation stage. The crushing stage plays the basic role. Typically, in the primary crushing, often use jaw crusher. Impact crusher is often used as secondary crushing machine in the process of sphalerite ore processing. The PE series impact crusher is very suitable for open-pit crushing in mineral processing plant. In the sphalerite ore processing plant, beneficiation machine is used to produce sphalerite concentrate. As for the sphalerite beneficiation machine, flotation machine plays an important role. And the flotation machine has high efficiency and low power consumption. Besides, sphalerite concentrate will be specially dried by dryer. So the dry products are finished.
 
However, in practice, the process must be taken according to the nature of the ore. It is impossible to recover and lose to tailings, and increase the dosage of collector, and make part of the flotation of pyrite, which is vicious circle of pyrite in the zinc circuit.
 
Sphalerite ore beneficiation equipment:
In the sphalerite ore mining processing, it should use many different kinds of equipment. In the crushing process, we can supply many crushing machines, include jaw crusher, impact crusher, hammer crusher, cone crusher. The most important crushing machine is impact crusher, we will recommend you PFW series impact crusher which is adopted by heavy-duty rotor design, unique hammer locking system, and interchangeable wearing parts. every PFW impact crusher can ensure excellent stableness and reliability. Then in the grinding process, we have ball mill, vertical mill and so on. In the beneficiation plant, we can provide you with flotation machine, jigger machine, magnetic separation equipment, etc. All equipments are high efficiency and low cost, they all adopt advanced technology and can work long time. We believe that the sphaleriteore processing plant will significantly improve the capacity of your quarry.
 
Henan Kefan is the professional ore processing plant manufacturer in China, we can design the unique ore dressing process for every customer, but also can manufacture many kinds of ore beneficiation equipments.
