relationship between copper ore grade and operating costs

relationship between copper ore grade and operating costs,Metal prices as a function of ore gradefrom mining lower grade ores (or deeper or thinner veins) can only be offset if technological progress is sufficiently rapid. A simple index of this process is the movement of the 'labour cost of resources', ie, the ratio of resource price to labour price. Table 1 is reproduced from. Nordhaus' article and shows the ratio of the prices.relationship between copper ore grade and operating costs,Decreasing Ore Grades in Global Metallic Mining - Semantic ScholarNov 7, 2016 . quantifies, on a global level, the relationship between ore grade and energy intensity.
