Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...

Desalination Fact Sheet

Desalination requires sophisticated plants that have high capital costs, significant maintenance requirements and shorter operating life than traditional water treatment plants. The saltier the water the more expensive it is to desalinate, so it may be cheaper to desalinate brackish (slightly salty) water or wastewater rather than seawater.
