Coral Bay Nickel Ore Cu Zn Pb Plant

The objectives of this study were to explore the influences of pH on the release of Cu, Zn, Cd, Pb, Ni, and Cr in sediments derived from the upstream, middle, and downstream reaches of Dongdagou stream in Gansu Province, Northwest China, and to examine the fractionation changes of heavy metals in the sediments after reaching their release equilibrium under different pH conditions.

A century long sedimentary record of anthropogenic

1. Introduction. Anthropogenic lead Pb has been an important contaminant in human history, especially after the Industrial Revolution. The emission of anthropogenic Pb reached a level greater than 20 times the global natural Pb emissions in the 1980s Nriagu, 1989, mainly attributable to usage of leaded gasoline, high-temperature industrial activities and incineration Komrek et al., 2008 ...

Water sediment - Gladstone Healthy Harbour

Nickel Ni the 24th most abundant metal in the Earths crust and is an essential trace metal for all organisms. Nickel in waterways can come from sources that are industrial e.g. industrial discharges, handling of coal or natural e.g. through weathering of rocks. In water, nickel is mostly adsorbed onto sediment and suspended particles.
