Estimation of Open Cut Mining Recovery and Mining Dilution

on bulk mining by calculating the dilution caused by the regularised cells “saw toothing” of the deposit boundaries. These Mining Recovery and Mining Dilution estimates will only be valid if the deposit is excavated by mining SMU blocks and not deposit boundaries as defined by grade control and survey.

HOW TO CALCULATE CORE RECOVERY AND RQD OF ROCK

Feb 06, 2016· Core Recovery and RQD (Rock Quality Designation) The easiest way to characterize the amount of material recovered during rock coring is to calculate “core recovery” as the amount (i.e. length) of recovered material divided by the total length of the core run (presented as a percentage). Rock Quality Designation (RQD) is a modified core recovery percentage in which the lengths of all sound

Ore Dilution & Recovery in Mining

Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or capping, and often clean ore can be obtained only by leaving some ore in the mine. In open-stope mines the greatest loss of ore is that tied up in pillars left for support of the back or hanging wall. The amount of ore thus left varies considerably

ore dilution and ore recovery SlideShare

Oct 04, 2019· ORE RECOVERY Ore recovery is based on the material within the model that is left behind to provide structural support, thereby not being recovered. The generalized equation for recovery is given in the following equation: More specifically, ore recovery can be defined by the percentage of minable reserves extracted in the mining process.

Mining Valuation Techniques P/NAV, P/CF, EV/Resource

This guide to mining valuation will teach you all you need to know to value an asset! The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mining plan produced in a technical report (like a Feasibility Study). Without such a study available, one has to resort to more crude

Room and pillar mining Wikipedia

Room and pillar (variant of breast stoping), is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. To do this, "rooms" of ore are dug out while "pillars" of untouched material are left to support the roof overburden.Calculating the size, shape, and position of pillars is a complicated procedure, and is an area of
