Gold(I) sulfide

Overview

The compound crystallizes in the motif seen for cuprous oxide gold is 2coordinate, sulfur 4coordinate, and the SAuS linkage is linear. Linear coordination geometry is typical of gold(I) compounds, e.g. the coordination complex chloro(dimethyl sulfide)gold(I). The structure is similar to the form of silver sulfide (argentite), which only exists at high temperatures.
It can be prepared by treating gold chloride with hydrogen sulfide It also arises by sulfiding dicyanoaurate

Acid mine drainage

Nomenclature

Acid mine drainage, acid and metalliferous drainage (AMD), or acid rock drainage (ARD) is the outflow of acidic water from metal mines or coal mines.
Acid rock drainage occurs naturally within some environments as part of the rock weathering process but is exacerbated by largescale earth disturbances characteristic of mining and other large construction activities, usually within rocks containing an abundance of sulfide minerals. Areas where the earth has b
