Limestone is a sedimentary rock made primarily from calcium carbonate, usually in the form of calcite and aragonite. Its grains vary in size and can consist of a variety of materials including shells, coral, and mud. It is typically off-white to gray in color and usually forms in shallow marine environments.

Phase 2 exploration also known as mid-stage or evaluation, at this stage the objective is to determine if the target has the potential size and grade to be economic. Programs at this stage will require focusing tools including recognizance drilling. Phase 3 exploration is also known as advanced stage or delineation.

In-furnace calcium injection desulfurization technology sends limestone powder or lime powder gas into the furnace. Under high temperature conditions, calcium carbonate decomposes to form CaO, and the generated CaO reacts with SO 2 to form calcium sulfate. This method has the characteristics of a low investment, low operating …

The most widely adopted method of limestone mining is through opencast pits with bench formation. Limestone mining causes widespread disturbance in the environment. Myriad impacts are observed as ...
The limestone averages 18.3 m (60 ft) in thickness, with mining planned in two lifts (i.e., initial development and benching). The height of the initial development was 7 m (23 ft). Secondary bench mining removed an additional 9.1 m (30 ft) from the floor, resulting in a total planned mining height of 16.2 m (53 ft).
