In mining applications, lime is used as a coagulation aid in thickeners and clarifiers. By adjusting the pH, lime will create the optimum conditions for flocculation and coagulation to occur as well as assist other reagents to perform their function. 


With an increase in pH, soluble calcium will become more mobile and modify fine particles in a way that improves settlement. This modification can also reduce the need for additional flocculants while improving the density and strength of the flocs.

A consistent and reliable milk of lime solution is required for coagulation purposes which can be manufactured using either hydrated lime or slaking quicklime on site. Graymont can assist customers to achieve the desired product and outcomes they require.

Limestone is composed of the mineral calcite (calcium carbonate) and/or the mineral dolomite (calcium and magnesium carbonate) along with small amounts of other minerals.
