Some observations on copper yields and ore grades ...

The average copper content of ore deposits is usually below the average yield of the ore accessed in the early years of production. The initial grades of new mines have not declined over the past forty years, and there has been no perceptible tendency for the average grade of porphyry deposits brought into production to decline over time.

2021-4-10  Copper Yields And Ore Grade. Learning goals what is an ore deposit ,typical mines today have ore grades of only 0.6 percent copper. since metal concentrations occur at much lower grades, the copper concentrations are measured in parts per million If a sample has pm copper, this means that in million lbs of rock, there is lb of copper.

Advanced Machine Learning Methods for Copper Ore

Ore grade estimation is one of the most important tasks in the design of effective strategies for the exploitation of mineral resources. In this work, we compare the accuracy of ordinary kriging with advanced machine learning techniques in the estimation of mineral grade as a function of the location in the deposit. As a case study, we analyze data from the Sarcheshmesh porphyry
