Fire Assay Information

2005-4-17A troy ounce is 1.097 ounces. Since mining companies need to know the content of salable material in their ore in usable numbers, such as ounces of gold per ton of ore, this makes conversion and reporting easy. So, the gold bead will usually weigh much less than 0.001 grams, more like 0.0001 grams.Get price
