    Mining Waste Products The types of waste materials generated are dependant upon the type of mining activity Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery ofArsenic Arsenic is one of the most important heavy metals causing disquiet from both ecological and individual health standpoints (Hughes et al, 1988)It has a semimetallic property, is prominently toxic and carcinogenic, and is extensively available in the form of oxides or sulfides or as a salt of iron, sodium, calcium, copper, etc (Singh et al, 2007)Toxicity, mechanism and health effects of some heavy metalsHeavy metals are naturally occurring elements that have a high atomic weight and a density at least 5 times greater than that of water Their multiple industrial, domestic, agricultural, medical and technological applications have led to their wide distribution in the environment; raising concerns over their potential effects on human health and the environmentHeavy Metals Toxicity and the Environment

  • A mineralogical perspective on the recovery of platinum

    Published studies dealing with the process mineralogy of Pt mines on the Bushveld Complex is generally limited to the Western Bushveld The recognition by mine management that another resource, in addition to the Upper Group 2 (UG2) reef currently being mined at the Two Rivers platinum mine (TRP), is urgently required in order to extend the life of mine, presentedThe most obvious impact to biodiversity from mining is the removal of vegetation, which in turn alters the availability of food and shelter for wildlife At a broader scale, mining may impact biodiversity by changing species composition and structure For example, acid drainage and high metal concentrations in rivers generally result in anAppendix 2: Environmental and Social Impacts of MiningMining continues to be a dangerous activity, whether largescale industrial mining or smallscale artisanal mining Not only are there accidents, but exposure to dust and toxins, along with stress from the working environment or managerial pressures, give rise to a range of diseases that affect miners I look at mining and health from various personal perspectives:Mining is bad for health: a voyage of discovery | SpringerLink

  • Calcium (Ca) and water Lenntech

    Calcium often positively affects soil quality and various compounds are applied as a fertilizer For example, CaCl 2or Ca(NO) 3 solutions are applied in horticulture Calcium oxide is a dehydrating molluscicide What are the environmental effects of calcium in water?
