  • Comparative Assessment of Heavy Metals in Drinking Water ...

    The study assessed levels of heavy metals in drinking water sources in two smallscale mining communities (Nangodi and Tinga) in northern Ghana. Seventytwo (72) water samples were collected from boreholes, hand dug wells, dugout, and a stream in the two mining communities. The levels of mercury (Hg), arsenic (As), lead (Pb), zinc (Zn), and cadmium (Cd) were determined using an atomic ...

  • The Mercury Problem in Artisanal and Small‐Scale Gold Mining

     · The Mercury Problem in Artisanal Gold Mining. Mercurybased artisanal and smallscale gold mining (ASGM) causes more mercury pollution than any other human activity. 1 In this practice, mercury metal is used to extract gold from ore as a stable amalgam. The amalgam is then heated to evaporate the mercury and isolate the gold.

  • Industrial and mining pollution and its effects final

     · Mining pollution Mining is the extraction of minerals and metals from the earth. Ores recovered by mining include metals, coal, gemstones, etc. Mining pollution occurs when mining generates large amount of waste discharges into the environment. Mining of stone and metal has been recorded since prehistoric times. Mining is of two types – surface mining and underground mining.
