The Bozshakol Clay Project in Kazakhstan includes the design of a processing plant with the capacity to process clay ore at a rate of 5 Mt/y. This plant upgrades the ore through standard copper flotation processes and provides concentrate streams that feed into the Bozshakol Sulphide plant at the appropriate locations (regrind circuit, concentrate circuit) depending on concentrate grade and size distribution.
The clay ore is reduced in size to a P80 of 50 mm through a Stammler and sizer before being converted into a slurry via a SAG mill. Fine clay material (<27 μm) is separated and sent to a fine flotation material while the coarser material is ground to a P80 of <53 μm via a ball mill prior to the flotation circuit. All tails streams are thickened before being pumped to the tailings storage facility. Click here learn more about Bozshakol Clay Project
