Hi, I am in the process of re opening an old silver mine. I got an assay on some mullock and It also contains 11% lead, 9% zinc, 6000gpt copper, 835 gpt silver. From the history they would crush and concentrate, Send of to cockle creek smelter. I remember here a while ago there were 2 silver miners in Tasmania that responded to a post. I meant to pm you at the time. I guess i am just wondering If someone can help me out a bit with the process. I have a jaw crusher, hammer mill. Some of The galena is in pieces 4 mm, do i still try and crush everything to sub 1mm before putting Over table like gold? I guess trial and error. I know there is a smelter in sa, any others that will Handle this type of ore? I will post some pics of ore later. Cheers.
