Limestone is used as the source for the production of precipitated calcium carbonate. Marble wastes primarily constitute of CaCO. 3. . As the major content of the marble waste and limestone are the same, marble wastes can be used as an alternative source for the production of precipitated calcium carbonate.

Description. Another type of process for the production of calcium hypochlorite involves separate preparations of sodium hypochloritesodium chloride solution and calcium hydroxide slurry. Part of the salt in the sodium hypochlorite sodium chloride solution is present as solid salt which is removed by means of a centrifuge (Equation 6).

The chemical composition and structure of slag are similar to those of cement and are generally expressed as xLi 2 O·yCaO·zAl 2 O 3 ·nSiO 2, . In this paper, the possibility of leaching aqueously of lithium from the slag mentioned above is going to be probed through chlorinating the insoluble lithium bound in slag by calcium chloride.

For every 8 tons of soda ash, the process produced tons of hydrogen chloride and 7 tons of calcium sulfide waste. This solid waste (known as galligu) had no economic value, and was piled in heaps and spread on fields near the soda works, where it weathered to release hydrogen sulfide, the toxic gas responsible for the odor of rotten eggs.

The Solvay process results in soda ash (predominantly sodium carbonate (Na 2 CO 3)) from brine (as a source of sodium chloride (NaCl)) and from limestone (as a source of calcium carbonate (CaCO 3)). The overall process is: 2 NaCl + CaCO 3 → Na 2 CO 3 + CaCl 2. The actual implementation of this global, overall reaction is intricate.
