Now let's assume that gold is valued at 1500 per ounce. That would make the gold in a one pound ore sample worth approximately 75 cents, and this is assuming that the ore is extremely rich. Many mines can run profitably on much lower grade ores, which might easily reduce the average value of ore down to 25 cents or less per pound.
Highend steel production at a low coke consumption level and high productivity rate can only be achieved by using highquality lumpy iron ore. As more pellets and sinter are used in the blast furnace burden, which leads to an increase in the quality restrictions for sinter fines and concentrate for pellets, economical beneficiation processes ...

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.

Chalcopyrite (or copper pyrite), looks like, and is easily confused with Pyrite, FeS2. Chalcopyrite is one of the minerals refered to as "Fool's Gold" because of its bright golden color. But real gold is a more buttery yellow and is ductile and malleable. As an ore od copper, the yield of chalcopyrite is rather low in terms of atoms per molecule.
copper products. Once mined, higher quality sulphide ores are processed into a more concentrated form, referred to as copper concentrates. This ore type is then refined via pyrometallurgy. Lowgrade sulphide ores and oxide ores are processed via heap leaching and typically refined via the increasingly popular hydrometallurgical approach SXEW.
