EP2512991A1

A method of producing calcium carbonate from a waste sludge containing calcium carbonate and at least one silicate mineral The method comprises the steps of: (i) incinerating the sludge to an ash in which at least 60 % of the calcium carbonate present in the sludge is converted to free calcium oxide which is unreacted with the silicate mineral(s), (ii) optionally slaking the ash to convert at ....

Lime (material)

The process by which limestone (calcium carbonate) is converted to quicklime by heating, then to slaked lime by hydration, and naturally reverts to calcium carbonate by carbonation is called the lime cycle The conditions and compounds present during each step of the lime cycle have a strong influence of the end product, thus the complex and varied physical nature of lime products...

US20180170765A1

The present invention relates to the use of a depolymerized carboxylated cellulose solution for preparing an aqueous Precipitated Calcium Carbonate (PCC) slurry by slaking a material containing calcium oxide in water, followed by carbonation of the milk of lime thus obtained The depolymerized carboxylated cellulose solution has a solid content of 25 wt % to 40 wt %, based on the total ....

Calcium Chloride

Calcium Chloride (CaCl 2) is an inorganic compound, marketed as 36% solution, 75-78% flakes or 94-97% granules, used for roads de-icing, dust control, brine refrigeration, dehumidification, setting time reduction in concrete, petroleum oil extraction and food processing Calcium chloride production process basically consists of limestone reaction with hydrochloric ac...

Calcium carbonate | CaCO3

Calcium carbonate appears as white, odorless powder or colorless crystals Practically insoluble in water Occurs extensive in rocks world-wide Ground calcium carbonate (CAS: 1317-65-3) results directly from the mining of limestone The extraction process keeps the carbonate very close to its original state of purity and delivers a finely ....

Calcium Formate Production Process

Precipitated Calcium Carbonate (PCC) - Manufacturing Process Precipitated Calcium Carbonate Production Precipitated calcium carbonate is produced using the most economic process existing today Limestone is converted into calcium oxide and carbon dioxide by means of calcination at temperatures in excess of 900°C...

Solvay process

The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3)The ammonia-soda process was developed into its modern form by Ernest Solvay during the 1860s The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries)...
