Apr 04, 2016  The maximum allowable Stripping Ratio (SR max) defines break even stripping ratio (BESR).This represents the highest possible units of waste that can be handled. If the SR exceeds the BESR then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining.

Stripping Ratio Mineral Production Activities ...

6. Stripping ratio . The main factor in designing a n open pit mine, which largely determines the cost of mining, is the stripping ratio.. Stripping is the removal of waste rock from above and around the orebody. Stripping ratio is defined as the tonnage of waste rock to be mined, divided by the tonnage of ore to be mined from the pit.

Stripping ratio - Wikipedia

In surface mining, stripping ratio or strip ratio refers to the amount of waste (or overburden) that must be removed to release a given ore quantity. It is a number or ratio that express how much waste is mined per unit of ore. The units of a stripping ratio can vary between mine types. For example, in coal mining the stripping ratio is commonly referred to as volume/weight. Whereas in metal mining, stripping ratio is unitless and is expressed as weight/weight. A stripping ratio can be expressed as a ratio or as a number.

When it comes to gold deposits, grade is NOT king - Stockhead

Nov 13, 2019  The ‘grade is king’ mantra is not always evident in open pit mines, says Ulrich — other factors, such as strip ratio, come into play. ‘Strip ratio’ refers to the ratio between the amount of waste (dirt or rock) that must be removed to extract one unit of gold-bearing ore. The lower it is the better. 3. Orebody Size Thickness.
