Assessing of Losses and Dilution Impact on the Cost Chain: Case Study of Gold Ore Deposits

The conditions of declining gold grade in the ore, increasing depth excavation, and de-creasing unallocated stock deposits make it necessary to develop efficient solutions for mine-to-mill process, which have be adapted each specific mining plant will optimizes production costs. Current research focuses on a case study that demonstrates how indicators losses dilution influence variation costs chain cycle. article examines topical issue determining effects at stages due changes dilution. author’s approach formation cost is proposed by integrating several estimation methods into general methodology. methodology compilation factor analysis engineering take account change It was proven with variations dilution, savings arise volume work ore averaging, transportation, beneficiation. For Kuranakh field, there are no stage. use internal reserves means managing quality parameters allows reducing per ton processed rock mass along entire chain.
