2009-11-12 Gypsum (CaSO4. 2H2O) is produced by increasingly more industrial processes, for instance, when calcium carbonate or lime is used to neutralize sulfuric acid containing effluents or when apatite (Ca3(PO4)2. CaF2. CaCO3), the raw material used in phosphoric acid
A brand new gypsum production process for the production of sulfuric acid co-production cement was successfully developed on March 5 in Nanchang, Jiangxi Province, and successfully passed the industrialization test to produce qualified sulfuric acid and cement products.
Production of Gypsum Products from Waste Battery Acid. sulphuric acid (H 2SO 4) from the batteries is neutralised with the aid of either calcium hydroxide (Ca (OH) 2) or calcium carbonate (CaCO 3) will produce gypsum (CaSO 4.2H 2O), a valuable product in plasterboard and cement production.

2015-2-12 Natural stone must be carefully quarried and preferably removed as large blocks. The first step is to take down the "primary block", which is a large dimensioned chunk of rock loosened from the quarry wall. This is most often achieved by drilling, blasting or/or sawing. A primary block can vary in size depending on the stone type, and up to 1000 cubic metres, 2700 tons!
2021-7-12 In the long-term mining and production process, a large number of waste rocks and tailings are produced, which can be completely or partially replaced by sand and gravel aggregate. Most waste rocks produced in the mining process can be used as a coarse and medium-grained aggregate.
