ore dilution and ore recovery
THE IMPORTANCE OF DILUTION FACTOR FOR OPEN PIT
In most cases, lower feed 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.
AN APPROACH ON DILUTION AND ORE RECOVERY/
Dilution and ore recovery/loss have an important role in calculation of mineral reserves. Each percent increase in dilution and decrease in recovery negatively affects economic value of the reserve. These parameters are mainly controlled by the
Reduce ore dilution and loss in open pit mines BMT
Ore loss occurs when material containing grade is incorrectly sent to a waste dump. When a cost is given for Ore Loss, it is the sale value of the metal recovered from this ore . Dilution occurs when waste is unintentionally with material containing ore and sent to the mill. When a cost is given for
Ore Dilution Recovery in Mining
05/04/2017· Recovery and dilution usually are interrelated; with some methods of stoping a high recovery involves contamination of the ore from the walls or
Ore Loss and Dilution A Mine Engineering Study
01/07/2018· Ore loss and dilution attributable to blast heave may be significant depending upon blast properties, fragmentation and the characteristic shapes of the ore type polygons outlined by dig lines.

Anaconda Mining increased ore recovery and reduced ...
Dilution was affecting mill feed grade. Ore production was falling because small ore polygons were not recoverable. The polygons, as small as two blast holes wide, were being entirely displaced from their in situ location by blast movement; Dilution, up to 20% 1, was affecting grades and ore recovery
Dilution and ore recovery QueensMineDesignWiki
mediawiki/...As a mining project is developed from conceptual to production phases, there exist a variety of uncertainties and difficulties that affect the operations designs and economic value. A notable design parameter to be taken into account is the factor of dilution. Dilution is the waste material not separated from the ore in the stagesore dilution and ore recovery SlideShare
04/10/2019· 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
