Aug 26, 2008 Mining is widely regarded as having adverse effects on environment of both magnitude and diversity. Some of these effects include erosion, formation of sinkhole, biodiversity loss and contamination of groundwater by chemical from the mining process in general and open-pit mining in particular. As such, a repeatable process to evaluate these effects primarily aims to diminish them.

Cast iron is an iron alloy containing 2 wt. – 4 wt. carbon, 1 wt. – 3 wt. silicon and smaller amounts of minor elements . In comparison, steel has a lower carbon content of up to 2 wt. and a lower silicon content. Cast iron can also be further optimized by alloying with small quantities of manganese, molybdenum, cerium, nickel, copper, vanadium and titanium before being cast.
