how dolomite is used and the process it takes

Dolomite differs from Limesand and Limestone in that it contains magnesium as well as calcium. It is used to supply both of these elements and is a very effective neutralizing agent.

However, dolomite is formed in limestone when the calcium ions replace magnesium ions in a process called 'dolomitization'. As a mineral compound that is rich in calcium and magnesium, dolomite lime can be used as a fertilizer for cannabis plants being grown in nutrient deficient soil by controlling pH levels.

Dolomite. The term dolomite is used both for the mineral dolomite (calcium magnesium carbonate [CaMg(CO 3) 2]) and for the rock dolomite, which consists mostly of the mineral dolomite. Dolomite rock is sometimes termed dolostone to distinguish it from the mineral dolomite, but the more confusing terminology is the more prevalent.
