The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.

Government-approved permits are required for all new and ongoing mining operations, including exploration activities. This permitting process ensures that environmental standards are maintained from the beginning to the end of mining and metal production operations.

Granite used for countertops begins with mining the stone, deep in the ground, and cutting it into slabs, typically 9 to 10 feet long and 5 to 6 feet wide. Most of the granite used as building materials originates from Brazil, but some varieties of brown granite come from China. Once mined, the slabs are saw-cut.

Mining is an inherently invasive process that can cause damage to a landscape in an area much larger than the mining site itself. The effects of this damage can continue years after a mine has shut down, including the addition to greenhouse gasses, death of flora and fauna, and erosion of land and habitat.

Environmental impacts of mining can occur at local, regional, and global scales through direct and indirect mining practices. Impacts can result in erosion, sinkholes, loss of biodiversity, or the contamination of soil, groundwater, and surface water by the chemicals emitted from mining processes. These processes also have an impact on the atmosphere from the emissions of carbon which have ...
