contact us· Understanding Mining Waste Management and Disposal Methods. Mining produces a lot of waste which needs to be handled properly. Improper mining waste disposal will lead to air, soil, and water pollution. Different types of mining include landfill mining, coal mining, oil and gas extraction, metal, and non-metal ore mining.
contact usLithium is considered a borderline strategically important metal for the UK due to the limited availability of primary deposits, of sufficient grade, for economic processing (Naden, 2012). The rising demand, of approximately 10% yearly, has promulgated investigations for the development of secondary sources of lithium in order to secure long term reserves for the UK and Europe (Jaskula, 2015).
