Whatever your sample weight is, divide it by a million and multiply it by the ppm value. ppm means parts per million. For example 7 ppm of 3400 ounces. That would be (3400/1000000)*7 = 0.0034*7=0.0238 ounces. If you have a ton of ore then a ppm is a gram. If you have a million ounces of ore then a ppm is one ounce.

As it depends on the mining company whether it reports its drill results in grams per tonne or ounces per tonne, remember the number 0.029, as you will need this to convert troy ounces into grams. On the break even analysis page, it is stated that 1 troy ounce equals 31.103481 grams per ton, which equals 34.2857 grams per tonne.
The greatest energy input in copper and gold production is required for the comminution and grinding processes. The energy audit of mainly Australian copper and gold mines shows that 36 % of the overall energy consumption is attributable to comminution [1]. Previous studies had shown values between 18 % and 50 %.
