Set the gold ore and a small quantity of lead in a cupel. Place the cupel in a blast furnace. Heat the mixture until the lead and gold ore liquefy. The blast furnace batters the cupel with hot air. The lead combines with other metals and forms oxide compounds that separate from the gold. This process works best with small quantities of gold ore.

Gold processing - Gold processing - Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Some early mills in Nevada (e.g., the Ophir Mill in Washoe Valley) used this process, but it rapidly lost out to the cheaper Washoe pan. Chlorine leaching, however, expanded into many areas of the American West and elsewhere during the nineteenth century and was used in some Nevada mills in the late twentieth century. Lixiviation mills, developed in the 1880s, leached complex ores with a ...

For those thinking about processing larger quantities of ore such as hundreds or even thousands of pounds of rock from mines, there are several manufacturers that sell small portable hammer and impact mills. These mechanized crushing systems can generate some very significant dust, and so when using them is important to consider methods for dust control or elimination.
