Ore Stockpiling – Why are we doing this again?

28.04.2016· In this blog I won't go into all the costs and environmental issues associated with stockpile operation. The discussion focuses on the reasons for stockpiling and why stockpiles can get large in size or numerous in quantity. In my experience there are four main reasons why ore stockpiling might be done. They are: 1. Campaigning: For metallurgical reasons if there are some ore types that can

Lecture 4: Mining waste

The amount of tailings that remain is controlled by what grade the ore is, meaning the percentage of valuable minerals in the ore. For example, if the grade of an ore is 1 percent copper, 99 percent of the total ore would be deposited as tailings. Iron ores generally have higher grades than sulphide or gold ores, often going over 50 per cent or more. Less tailings are therefore generally
