Miller process . Other articles where Miller process is discussed: gold processing: History: Miller''s process of refining impure gold with chlorine gas (patented in Britain in 1867) and Emil Wohlwill''s electrorefining process (introduced in Hamburg, Ger., in 1878), it became possible routinely to achieve higher purities than had been allowed by fire refining.
Recovery of Gold from Incinerated Sewage Sludge Ash . In a series of studies into the development of an efficient and selective recovery process for gold that eliminates the need for water, the release behavior of gold from an incinerated sewage sludge ash heated to between 100 and 1000 C under a chlorine gas stream was investigated.
Miller Chlorination Process. A pyrometallurgical chlorination process, the Miller process is one of the oldest and most widely used processes in large scale gold refining. It involves bubbling chlorine gas through molten bullion.
The mean amount of gold refined per annum during five years (189195) was 949,527 ozs., containing gold, silver, and base metals (by difference) The mean assay of the refined gold for the same period was, and the mean loss of gold in the refining operations for the same period was per thousand.

Jun 07, 2013· Chlorine was used to displace air from the tube at lower temperatures (the rate of reaction is minimal at less than 400 C). The reaction depends upon diffusion of hot chlorine into the rhodium sponge, so periodically rotating the tube (caution! the glass will not appear hot in welllit conditions!) helps complete the chlorination.
