Fluorspar CaF2 75% Above

Fluorite is the raw material for producing hydrofluoric acid. Hydrofluoric acid is produced by the reaction of acid grade fluorite (fluorspar concentrate) with sulfuric acid in a heating furnace or tank.

• Color: green / white / purple / pink etc.
• Packing: tons of packages (can be packed according to customer requirements)
• Stocking cycle: 7-15 days (depending on the order quantity or customer requirements)

Grey Limestone

The main component of limestone is calcium carbonate (CaCO3). Lime and limestone are a large amount of raw materials used in construction materials and industry. Ironmaking uses limestone as flux to remove gangue. Steelmaking uses quicklime as slag-making material to remove harmful impurities such as sulfur and phosphorus.

• color: gray.
• Grade: ≥53% (limestone mine) Test: ASTM C25-17
• Granules: 40mm-80mm 90% min. Stocking cycle: 25-35 days (depending on the order quantity or customer requirements)

Rock crystle lump

Rock (rock crystal) is a rare mineral, a type of gemstone, quartz crystal, mineralogy belongs to the quartz family. The main chemical composition is silicon dioxide and the chemical formula is SiO2. When pure, it forms colorless and transparent crystals. When it contains trace elements Al, Fe, etc., it is pink, purple, yellow, brown, etc. Irradiated trace elements form different types of color centers and produce different colors, such as purple, yellow, brown, pink, etc. Inclusion crystals containing associated minerals are called inclusion crystals, such as hair crystals, green ghosts, red rabbit hair, etc. The inclusions are rutile, tourmaline, actinolite, mica, chlorite, etc.

Calcium carbide lump

Calcium carbide, the main component of calcium carbide, is an inorganic compound, white crystals, industrial products are gray-black blocks, and the cross-section is purple or gray. In case of water, a violent reaction occurs immediately, acetylene is generated, and heat is released. Calcium carbide is an important basic chemical raw material, mainly used to produce acetylene gas. It is also used for organic synthesis, oxyacetylene welding, etc.

• Color: gray or gray black
• Granules: 50MM-80MM 90% min or 80-120MM 100 kg or 50 kg iron drum packaging, GAS YIELD 295L / Kg

Sulphur pyrites

Pure pyrite contains 46.67% iron and 53.33% sulfur. Pyrite is generally used as a raw material for producing sulfur and sulfuric acid, rather than as a raw material for iron extraction, because iron extraction has better iron ore. Pyrite is unstable in the oxidation zone and easily decomposes to form iron hydroxide such as goethite and lepidocene.

• color: gray
• Sulfur grade: ≥48% Test: ASTM C25-17
• Particles: 200 mesh or less 20% max. Humidity: less than 10% Stocking cycle: 35-40 days (depending on the order quantity or customer requirements)
