    Concentrate grade ranged from 986 to 312 g/t gold At a US$1,200 gold price, the contained value of At a US$1,200 gold price, the contained value of these concentrates range from $3,800

    The gold grade of the cleaner concentrates ranged from 39 g/t Au to 84 g/t Au and the sulphur grade ranged from 21% S to 36 % S These grades of gold and sulphur are amenable to toll smelting through copper smelting operationsA concentrate grade is the gold content in the concentrate and usually is expressed in grams per tonne (g/t) or ounces per tonne (oz/t) the ratio of concentration is the proportion of the weight of the feed to the weight of the concentrate For example, if 500 tonnes ore feed are processed and 100 kilos of concentrate is obtained, the ratio of concentration is 5,000 If we compare this value.

    Gold grade of the head flotation concentrate was 296 g/t The concentrate size was 80% -80 um The concentrate size was 80% -80 um Mineral composition of the concentrate comprises 17% of rock-forming minerals, 59% of pyrite and 24%Nor is the formula dependable in a milling operation, for example, which yields only a table lead concentrate containing silver, lead, and zinc, and a flotation concentrate only slightly different in grade, for in this case there is no metal which has been rejected in one product and concentrated in a second This is not to suggest that the formulas will not give reliable results in such cases.
