Fluorite manufacturing method

Fluorite, also known as fluorite, is a common mineral, the main component is calcium fluoride (CaF2). It is widely used in the field of chemical production raw materials, mainly for the manufacture of hydrofluoric acid, and then the production of various fluoride. Below we will introduce the manufacturing method of fluorite in detail.

1. Ore Collection

First, ore containing fluorite components needs to be collected. Fluorite ore usually exists in the form of crystals, color diversity, colorless, green, purple, blue and so on. The collected ore needs to go through crushing, screening and other steps to obtain the appropriate particle size of raw materials.

2. calcination

high-temperature calcination of the screened fluorite ore, the calcination temperature is generally 900-1200 ° C, so that the calcium fluoride in the ore is decomposed into calcium oxide and fluorine gas.

3. Hydration

The calcined ore is cooled and then hydrated to react calcium oxide with water to produce calcium hydroxide. The

4. acidolysis

reacts calcium hydroxide with sulfuric acid or hydrochloric acid to form calcium sulfate or calcium chloride with release of hydrogen fluoride gas. This reaction step needs to be carried out in a sealed environment to avoid leakage of hydrogen fluoride gas.

5. Purification

The hydrogen fluoride gas is purified by a purification method to obtain high-purity hydrogen fluoride. This step usually requires the use of special equipment and technology to ensure the purity of the product.

6. conversion

high purity hydrogen fluoride gas can be converted into liquid hydrofluoric acid, which is an important raw material for the production of many chemicals.

above is the basic manufacturing method of fluorite. In the actual production process, the specific steps and parameters may vary due to different processes and equipment. In addition, some waste and by-products will be produced in the fluorite manufacturing process, which need to be properly treated and used to avoid environmental pollution.

need to pay attention to safety issues in the process of manufacturing fluorite. Hydrogen fluoride is a toxic and corrosive gas that requires strict sealing and operating regulations to avoid hazards to workers and the environment. Therefore, the production process must comply with the relevant environmental and safety standards.

In general, the manufacture of fluorite requires certain technology and equipment, while taking into account environmental protection and safety factors. Only in this way can we ensure that the manufacturing process of fluorite is economical and effective, and provide stable and high-quality raw materials for chemical production.
