Mobile and Modular Process Plants (3 replies)

Might is be for base metal recovery by flotation or gold by leaching and flotation, a Mobile and Modular Process Plants only use to be a thing of the pass... no more.

While gold and other placer operations (diamonds) are the big users in numbers of mobile plants, many other mining sectors could make use of them. Very good examples are rare earths and beach sands both of which tend to be lower tonnages. I can remember adverts for the "Polaris" caravan plant mounted on a series of Mercedes truck beds in the early 70's when I was at University. In South Africa in the 80's Gencor built a dual coal/diamond 50 tph cyclone plant based on 40 foot standard shipping container sized modules.

A brief google search ( shows a lot of plants from all over the world. AS it has been mentioned in other posts, selecting a vendor who truly understands his equipment and is close to your site can be a big help.

There have always been portable plants. Here on the Pacific coast someone did a study for a barge mounted plant to process small (<20,000 tonne) deposits decades ago. The idea folded due to the liability of permitting tiny tailings ponds.

Banks island gold currently runs 400 tpd through a modular plant. A portable dense media separator feeds 200 tpd grinding, gravity, and flotation modules that are trailer mounted by Sepro. Only the bins, thickeners and filters do not have wheels. When mining ceases the entire inventory can be sold elsewhere except for the concrete foundations

The old Yuba Manufacturing company which operated from the late 1890's to about 1960 built many floating dredges that also include a gravity circuit on them. I used to have a picture showing four or five of them operating on a tin deposit in Indonesia in the 1950's. There is still on operating on gold today on Near Marysville, California

There are also a couple of diamond dredges operating off southern Africa with a gravity circuit aboard.

So the concept is viable, and can be an easy way to get into operation.
