Gold is found in many forms from disseminated fine-grained gold up to very coarse gold visible with the naked eye. These variations in gold deportment necessitate early ore characterisation. A well-designed screen fire assay program paired with robust geology models can aid in identifying the proportion and location of coarse gold within a deposit.
The gold bead remaining in the crucible is washed and annealed on a hotplate to consolidate the gold, transferred to the electrobalance, and weighed to the nearest 0.001 mg. In the example in figure 25 the weight of the bead is 0.017 mg, which is equal to the ounces of gold per ton of ore, if an assay ton, 29.167 grams of ore, is assayed.
