Inert wastes from mining and quarrying operations, such as slate quarry waste and certain colliery shales, seem to be good materials for reclaiming wastes contaminated by copper, lead, and zinc. Organic wastes, such as sewage sludge and domestic refuse, may provide only a temporary visual improvement and stabilization of the toxic materials.

Application of Biochar in the Remediation of

Soil contamination in the Panjiachong lead and zinc mining areas has become a severe problem in Hunan Province, China. As the traditional stabilization technology comes with soil degradation, it is urgent to find a novel binder that is more eco-friendly. It has been proved that biochar can immobilize heavy metals, but limited research has been conducted on the contaminated soil with high

‘A contaminated mess’: how a Yukon mine left behind

2020-6-9  Yukon’s Wolverine mine, which primarily extracted zinc before it closed in 2015, has a storied history of failure. It opened and closed with only a few years of production, due to plummeting stocks. It left a flooded underground shaft and contaminated water in its wake.

Remediation of soil contaminated with arsenic, zinc,

In this study, soil contaminated with arsenic, nickel, and zinc was obtained from a closed iron/serpentine mining area. The H 2 SO 4 and H 3 PO 4 wash solutions, including the competitive oxyanion, enhanced the removal of arsenic. The acid attack on arsenic binding in the Fe/Mn oxide and organic/sulfides fractions may be a possible removal

Cadmium Toxicity: Where is Cadmium Found?

Cadmium can also enter the food chain from water. In Japan, zinc mining operations contaminated the local water supplies with cadmium. Local farmers used that water for irrigation of their fields. The soil became contaminated with cadmium which led to the uptake of cadmium into their rice (Jarup 2002).
