grade means lower mill recovery. Dilution also increases the cut-off grade which in turn reduces the overall ore utilization of a mine. In some cases, to take advantage of economies of scale, mining operations tend to plan for higher mining rates. Moving to a larger scale of operation means less selectivity, hence more dilution.

Example: For i = 7% and N = 5 years, the capital recovery factor is equal to 0.2439. A $1000 loan at 7% interest could therefore be paid back with five annual payments of $243.90. The present value of the five annual payments of $243.90 is $1000.. See also. Sinking Fund Factor

Estimation of Open Cut Mining Recovery and Mining Dilution By Kent Bannister, ARMIT, FAusIMM (CP), CEO Kent Bannister Pty Ltd, (KBPL) Summary Loss and dilution of Mineral Resource grade occurs during mining activities. Mining Recovery and Mining Dilution estimates are a required consideration in the reporting of Ore Reserves for mineral projects.

No mining loss or recovery factor has been considered in the estimation of the Ore Reserve. This is considered consistent with the latest grade control and reconciliation data available from the existing operation and is consistent with the suitability of earthmoving equipment to the orebody type (low to moderate grade and wide mineralised zones).

The theory of mine call factor (MCF) compares the sum of metal produced in recovery plus residue to the metal called for by the mines evaluation methods expressed as a percentage. The concept is well known in underground mining scenarios and therefore this article highlights some MCF issues from a ...

Recovery Factor = -202.7 + 54.1 × (bitumen grade) – 2.5 × (bitumen grade) 2. With the bitumen grades from Alberta's oil sands mining projects ranging from 10 to 13%, recovery factors are expected to exceed 88% to meet Directive 82, and in practice, often exceed 90%.

recovery factor 1. Measure of extraction efficiency. 2. In mining, the percentage of metal derived from an ore, or coal from a coal seam, etc. 3.
