Calcium Oxide, commonly known as quicklime, which is produced by burning the limestone containing Calcium Carbonate - the chemical process is called “calcination”.
Quicklime substance is caustic, alkaline and white powder that strongly reacts with water to form calcium hydroxide also known as “Quicklime”. It is pulverizing with water into special sizes, separating it from the dust, and putting it in oven. After that, occurring the acidification, calcination, and cooling process repeatedly at temperature up to 1250 C. Then, calcium carbonate transformed into Calcium Oxide (Quicklime). Also, it can be filled in big bags with capacity start from 25 kg to 50 kg, and ton and a half.








It is used in many industries, such as: Iron, steel, glass, paper, sugar production, leather tanning, treatment of sewage, processing industrial waste and the preparation of some dyes and bleaches. In addition, it is cast-off in extract minerals, acidic soils and as an adjunct to the fertilizer into the soil.
The limestone is heating in special furnaces called “lime kilns”, and then dissolves it through a reaction known as the (Thermal Analyzer).

Chemical Equation:

Calcium Carbonate → Calcium oxide + Carbon Dioxide
CaCO3(s) → CaO(s) + CO2(g)

Astra Lime – Quick

Astra Mining is ASTRA LIME- Quick

The Astra Mining dealing with limestone called (Astra Lime) as a brand, to serve directly the local market, Middle East and North Africa (MENA). As a first step to classify it according to measurement, components, crunching, and filtering to serve its customers.
