Feb 21, 2019 On the impacts of mining. Mining activities, including prospecting, exploration, construction, operation, maintenance, expansion, abandonment, decommissioning and repurposing of a mine can impact social and environmental systems in a range of positive and negative, and direct and indirect ways. Mine exploration, construction, operation, and maintenance may result in land-use change, and may have associated negative impacts on environmentsGet Price
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 habitatGet Price

extracted ending up as waste. By contrast, iron mining is less wasteful, with approximately 60 percent of the ore extracted processed as waste (Da Rosa, 1997; Sampat, 2003). Disposing of such large quantities of waste poses tremendous challenges for the mining industry and may significantly impact the environment. The impacts are often moreGet Price
Environmental hazards are present during every step of the open-pit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose radioactive elements, asbestos-like minerals, and metallic dust. During separation, residual rock slurries, which are mixtures of pulverized rock andGet Price
Mineral exploitation contributes significantly to economic growth and development in most world economies.

Jaw crusher is a main type of rock crusher used to crush minerals or stones into smaller sizes. It is an essential machine in a wide range of fields such as mining, quarrying and construction industries. Jaw crushers are usually used together with cone crushers, impact crushers and sand making machines to form a sandstone production line. Jaw crusher is used to crush various mineral rocks with compressive strength not exceeding 320MPa, such as cobblestone, calcite,granite, aggregate,quartz, concrete, dolomite, blue stone, iron ore, limestone, construction waste, etc.
