Process Description
1. Stage-grinding to Reduce Subsequent Workload and Costs
In the first grinding and classification stage, ball mill and hydrocyclone consists the closed circuit. It guarantees the classification efficiency and classification particle size. At the same time, it separates part of regular concentrates at advance. Part of low-grade tailings are discarded by high-gradient magnetic separator. It can reduce the middling regrinding amount and metal loss, also avoiding overgrinding.
2. Magnetic Separation – Flotation Combined Processing Technology, Environmental Friendly
The magnetic separation can separate regular coarse concentrates and tailings in time, which fits the principle of early recovery and early discarding as possible. It also reduces the flotation workload and costs.
3. Strong Magnetic Discarding to Provide Flotation Condition
Strong magnetic separation can recover the fine particle iron ore. It has double effects of desliming and discarding tailings. It can provide good conditions for flotation operation.
4. Verse Flotation to Float the Less Part
Verse flotation has a simple reagent system, which can obviously reduce the flotation reagent into the slurry. It can reduce the adverse reactions of flotation.
Introduction
A hematite separation production line is employed to extract and process hematite iron ore to produce hematite concentrate, which has numerous applications in various industries. Here are the primary uses of hematite and the production line’s overall utility:
Uses of Hematite
- Steel Production:
- Iron Ore Source: Hematite is a primary source of iron for the steel industry. The high iron content makes it ideal for producing pig iron, which is then used to make steel.
- Blast Furnaces: Hematite is used in blast furnaces to produce molten iron, which is further refined to produce various types of steel.
- Pigments:
- Red Pigment: Hematite’s natural red color is used as a pigment in paints, coatings, and cosmetics.
- Cement Coloring: Used as a coloring agent in the manufacture of colored cements.
- Heavy Media Separation:
- Dense Media Separation (DMS): Hematite is used in the mining industry to separate valuable minerals from gangue using a dense medium.
- Jewelry and Ornamental Stones:
- Gemstones: Hematite is cut, polished, and used in jewelry for its metallic luster and unique appearance.
- Decorative Items: Used in making beads, carvings, and other decorative objects.
- Radiation Shielding:
- Concrete Additive: Hematite is used as an aggregate in radiation shielding concrete, enhancing its density and effectiveness.
- Water Treatment:
- Adsorbent: Hematite can be used to remove heavy metals and other contaminants from water through adsorption processes.
