By 2000 bc the process of purifying gold silver alloys with salt to remove the silver was developed. The mining of alluvial deposits and, later, lode or vein deposits required crushing prior to gold extraction, and this consumed immense amounts of manpower. By ad 100, up to 40,000 slaves were employed in gold mining in Spain. The advent of Christianity somewhat tempered the demand for gold until about the

Silver processing Britannica

A process routinely employed in the fire assaying of gold ores is the addition of silver prior to fusion of the ore in order to ensure that the silver content of the final bead is high enough to dissolve. This is called inquartation, and the separating of silver and gold by leaching with nitric acid is referred to as parting.
