calcite for calcium carbonate production Lebanon

In the application of the present invention for the production of high purity calcium carbonate in which the calcite crystal form predominates it is preferred to have the calcium in a solution in which the concentration is greater than 5 mass to mass CaOH 2 in H 2 O and to carbonate the solution at a rate of less than or equal to

Calcium carbonate is used in paper mill as a filler material in the alkaline papermaking process Now a days Calcium carbonate dominant over other papermaking filler materials though at the first stage of papermaking kaolin was 1st choice The main reason behind the preference of calcium carbonate is the demand for brighter and bulkier paper There are significant benefits to the use of
