EP2512991A1 - Production of calcium carbonate from

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 ...

Kinetics of calcium carbonate precipitation through CO2 ...

2014-9-25  1. Introduction. In soda ash production through Solvay process, a waste stream of 10 m 3 per ton of product Na 2 CO 3 is produced. This stream, known as distiller waste, contains CaCl 2, NaCl, and small quantities of Ca(OH) 2 and CaCO 3.After precipitation of solid wastes from the stream, the remainder solution is discharged into sea, lakes or rivers, contaminating the environment .

Synthesis of aragonite-precipitated calcium carbonate

2016-12-9  The obtained aragonite-precipitated calcium carbonate (PCC) is characterized by XRD and SEM, which is used to assess the morphology and particle size. Using the proposed process, oyster shell waste powder was calcined at 1,000 °C for 2 h, after which the calcined shell powder was dissolved in water for hydration.

Influence of Ground Calcium Carbonate Waste on the ...

Ground calcium carbonate waste (GCW) is the by-product of the mining of calcium carbonate (CaCO 3) in the color pigment manufacturing industry. Both BA and RHA are classified as low-quality pozzolanic materials, differing from GCW, which contains a high calcium oxide (CaO) content that leads to products equivalent to the hydration reaction.
