which will help you to decide where to drill. Copper grade is the concentration of copper in the ore rock. To calculate the grade of copper for the sample, geologists use the equation: (amount of copper metal/amount of copper ore rock)*100 2. If a deposit area has 200lbs of copper in 10,000lbs of ore rock, what is the grade? 200/10000*100=2% 3.

(28 June 2021) Zinc prices showed 50% growth year-over-year in May 2021, an increase to $2,965 per metric ton from $1,975 in May 2020. The increase followed a two-year decline of 45% from the ten-year high of $3,500 in 2018. The price is currently 11.5% above the 5-year moving average — a figure analysts were not expecting, since zinc demand is declining in the era of COVID-19.

Zinc ores with coppers were smelted by the Romans, and metallic zinc was produced in India as early as the 1300 AD. Europe had to import the material from the subcontinent. Finally, the Europeans found a commercially viable way to extract the metal from a charcoal and calamine mixture in 1852. Below is the historical Zinc price per metric ton.

Until 1968, zinc royalty was fixed on an ad valorem basis at 7% of the average sale price. From 1968-1997, the rates were based on tonnage regimes and were changed to ad valorem basis (linked with the LME prices) from 2000. Currently, the royalty is set at 9.5% of the LME zinc metal price chargeable on the zinc metal contained in the ore.
