2021-4-18 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

2021-4-14 Chemical properties. The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H
Nauru is most famous as a producer and exporter of phosphate. In 1899, an administrator from the Pacific Islands Company suspected a substance found on the island was phosphate.

common are environmental permits and environmental impact assessments. Mining companies typically are required to obtain environmental permits signifying government approval of various aspects of their mine plans, including those for reclamation, waste disposal, sewage treatment, drinking water, and construction of dams and other impoundments.
Mining regions are now often located in remote areas of north of Canada and Australia, and in developing countries in South America, Asia, and Africa, often with less stringent mining laws and weaker environmental regulations (Miranda et al. 1998; World Bank, 2002, 2017a). Mining impacts, including waste streams and social impacts, were
