Alkanol amines are useful in this invention as grinding aids for grinding silica-containing solids. It is preferred that the alkanol amines used in the practice of this invention are lower alkanol amines having from about one to about six carbon atoms. In a preferred embodiment, the alkanol amines correspond to the formula (R) x NH (3-x)
Cement grinding aids are classified into three key types based on the feedstock, such as amine-based, alcohol-based and ether-based grinding aids. The prime factor behind the usage of cement grinding aids is the elimination of the coating effect of clinker on grinding mill walls and to increase the production rate of cement keeping the surface area constant.
The grinding process of this invention is useful in the grinding of solids containing silica or siliceous gangue. It is surprising that the use of a small amount of an alkanol amine results in more efficient grinding. It has also been found that the alkanol amine grinding aid does not detrimentally affect further processing of the treated ores.
