gold mining, large quantities of waste are produced. Over 99% of extracted ore in gold mining are released into the surrounding environment as waste [8]. One of the wastes that have been implied around mining sites is heavy metals. Heavy metals have received global attention of researchers, owing to their deleterious effects on plants,

· KEY WORDS: Water quality, heavy metals, mining, cumulative effects, Peru, water contamination ABSTRACT The Rimac river provides drinking water to Lima, the capital of Peru. Mines upstream release heavy metals into the river, but these can also be introduced by natural leaching, informal mining, and waste from previous mines. The effect of mining on water resources in Peru .

· This is the first documentation of an outbreak of childhood lead poisoning associated with artisanal gold mining in Artisanal gold mining is dangerous to human health, as heavy metals, mainly Hg, Pb, and arsenic (As) are often released into the environment. The Igun gold mine is loed in the southwestern schist belt of Nigeria.
Placer gold mining, which extracts gold from buried or exposed alluvia, is often conducted on or near streams. Such mining has the potential to adversely affect water quality. Other heavy metals associated with the gold (such as arsenic, cadmium, lead, zinc, and copper) may be freed to enter streams. Mercury may also enter streams if miners are using it to recover fine particles of gold. These ...
· Associated Minerals: Placer gold invariably is accompanied by other heavy minerals, which comprise the black, white, or yellow concentrates found in the sluice box when cleaning 3 lists these minerals roughly in the order of their commonness. Some of the characteristics noted under Remarks apply chiefly to the minerals as they are found in sluicebox concentrates.
Heavy Metal Mines in the Ochil Hills: Chronology and Context By John G Harrison INTRODUCTION In recent decades the mines of the Ochil Hills, in east central Scotland, have attracted the interest of speleologists, mineralogists, ceramists, and botanists1. In the past they attracted the notice of an industrial spy, of speculators and landowners and of the British government, represented by Sir ...

Mining and ore excavation can cause the acidifiion and heavy metal pollution of downstream water systems. It can be difficult to assess the load contributions from individual mining areas, which is commonly required for environmental impact assessments. In the current study, we quantified the net impact of the unmonitored mining activities in the Zaamar Goldfield (Mongolia) on heavy metal ...
and gold in the last decades has severely polluted the natural environments surrounding mine fields with considerable amounts of heavy metals. The mining garbage will lead to the concentration of elements in soils that could be leached towards aquatic environments. Thus, soils in mining areas need to be monitored in view to control the le

We hypothesized that in the rural southwestern portion of Ghana, the lack of industrial activities makes artisanal gold mining (AGM) by Hg amalgamation the main source of water resource contamination with heavy metals. Therefore, metals showing concentration trends similar to that of Hg in the studied system are likely impacted by AGM. We found ...
Gold mining has played a significant role in the socio economic life of Ghana for the past years (Akabzaa et al. 2007). Activities associated with mining and mineral processing operations have significant potential to pollute both surface and groundwater either directly or indirectly. Mining by its nature has been known to consume and divert water and can seriously pollute water resources ...
