    What are the main methods of mining?

    In-situ mining, which is primarily used in mining uranium, involves dissolving the mineral resource in place then processing it at the surface without moving rock from the ground. The method used depends on the type of mineral resource that is mined, its location at or beneath the surface, and whether the resource is worth enough money to justify extracting it.

    Environmental impact of mining

    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

    Gold Mining

    Gold mining is a global business with operations on every continent, except Antarctica, and gold is extracted from mines of widely varying types and scale. Mines and gold mining operations have become increasingly geographically diverse, far removed from the concentrated supply of four decades or so ago when the vast majority of the world's gold came from South Africa.

    How Underground Mining Works

    There are hard-rock underground mines, and there are soft-rock underground mines. Coal deposits, for instance, live in relatively soft sedimentary rock. Gold deposits live in igneous or metamorphic rock, which is relatively hard, as do diamonds, copper, silver, nickel and zinc [source: Great Mining].

    How Mining Companies are Reducing the

    Mining leaves an eyesore on the land. By ripping open mountains to extract the ores within, it sometimes leaves areas unusable after the mining companies have left.

    Impacts of copper mining on people and nature

    The mining industry uses sulphuric acid in the extraction and treatment of copper. The extraction processes are called heap and situ leaching; during these processes, particles react with each other to create acidic mists that not only harm people's skin, eyes and lungs, but also destroy crops, deteriorate the quality of the land, and damage nearby buildings.
