Dolomite

Jack Ceramic supplies industrial dolomite mined in China and processed to meet standard mineral specifications. The product is offered in high‑purity grades with calcium and magnesium contents that typically exceed 90 % combined CaO + MgO. Particle size can be supplied from coarse fractions of 2 mm down to fine powders of 75 µm, according to buyer requirement. The chemical composition includes calcium carbonate and magnesium carbonate in a roughly 1:1 ratio, a characteristic that supports its performance in refractory applications.

In the glass‑making sector dolomite acts as a flux, while in ceramics it provides magnesium for colour stability and strength. Standard industry practice grades dolomite by purity, with typical bulk density around 2.8 t/m³ and moisture content below 1 %. Agricultural users employ dolomite as a soil conditioner to raise pH and supply magnesium to crops.

Jack Ceramic states that orders can be shipped on FOB or CIF terms, with packaging in bulk bags or 25 kg sacks. Because the supplier does not disclose a minimum order quantity, buyers should confirm the MOQ directly before placing a contract. Payment is usually arranged via T/T against copy of the commercial invoice, but the exact terms must be agreed with the supplier.
