Coated Calcium Carbonate

This product is ultrafine, surface treated calcium carbonate powder with stearic acid obtained from high purity white marble sources of Moroto.
The chemical description is the same as for ground calcium carbonate


Two types of lime are manufactured: Quick and hydrated lime.
For Quick lime, calcium carbonate undergoes high temperatures to produce calcium oxide.
Quick lime is mainly used in industry as a catalytic agent. Its also used in steel making. Air pollution control, paper industry , refining metals and making fiber glass.
For Hydrated lime, calcium oxide is mixed with a known amount of water to produce calcium hydroxide.

applied environmental purification as waste water treatment, agriculture to reduce soil acidity and construction as an essential ingredient in mortar, plaster etc.

4. Kaolin Powder

This is manufactured from crushed soapstone obtained from high grade talc sources of Kenya. Its applied in soap making industry as a filler and pesticide industry as a carrier.
Kaolin powder is made in two forms:
