ProExMin offers the opportunity to get in contact with a few former processing plant operators, mainly located in southern Europe. The mines have produced lead-zinc, tin-wolfram, and barite / fluorite concentrates.
It's a pity to see the equipment slowly rotting and the machinery might be demolished and destroyed. We have in our database a few former processing sites and the list will become longer and longer. If you are interested in these issue, please write us an E-mail and let's see what can be done!
