There are six parallel conventional milling circuits at Palabora Mining Company. Each milling circuit consists of a rod mill followed by a ball mill in series. Crusher product (9 mm) is fed to the rod mill, and the water is fed in ratio to the ore feed mass. The rod mill discharge is pumped, without any further water addition, to the first ball mill.

In this circuit primary crusher product is reduced to a HPGR circuit feed P80 of 35 mm by closed circuit secondary crushing. The HPGR is also in closed circuit and reduces the 35 mm feed to a circuit product P80 of 4 mm. This is then fed to a closed circuit ball mill which takes the grind down to a .

The grinding circuit consists of an SABC circuit, with a SAG mill followed by a ball mill and a pebble crusher to crush the SAG mill trommel oversize material. Primary crushed ore is reclaimed from the stockpile via two apron feeders which can operate individually or in parallel to provide the 385 t/h. The mill feed is conveyed to the primary

The circuit consists of topsize control crushing ahead of semiautogenous milling, which also incorporates pebble crushing. A portion of the SAG mill feed is crushed to –25mm to increase throughput through the mill. Product from the SAG mill circuit is further ground in ball mills, before being delivered to the flotation circuit. Flotation

coarse primary mill product is required or where the use of a DMS plant has necessitated the partial crushing of the ore. Secondary milling Another mode of occurrence of pgms in these reefs are as partiallylocked particles in the silicate minerals and this can influence the design of the minerals processing circuit if this mode is significant.

AG/SAG Mill. AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.

crushing circuit significantly compared with the conforming 3 stage crushing and ball milling design. The grate discharge ball mill in the conforming bid was replaced with a refurbished m diameter x m EGL SAG mill with 515 kW of installed power. A VVVF drive .

Apr 04, 2000· The present invention relates to froth flotation separation of minerals and in particular froth flotation of chalcopyrite, pentlandite, chalcocite, and platinum group metalbearing minerals. BACKGROUND OF THE INVENTION. Platinum group metals (PGM) occur in mainly two forms, as discrete minerals and in solid solution in basemetal sulfides.

Crushing and Screening Milling Flotation Tailings Disposal Concentrate Filtration and Dispatch Reagent Make Up and Dosing. RunofMine (RoM) ore at a top size of 350mm, from underground, will be conveyed to either one of two 6500t RoM silos for storage prior to the crushing circuit.

filtration. Grinding is carried out in a fully autogenous (AG) mill. The mill operates in closed circuit with a pebble crusher. Throughput is approximately 380 tph. Cyclone overflow from the grinding circuit is fed into a flotation circuit for the recovery of lead, zinc and silver. Two concentrates are produced (lead and

The ore is first crushed in a series of jaw crushers and fed to the primary and then the secondary ball mills which are in closed circuit with hydrocyclone classifiers. This is followed by gravity concentration on corduroy tables to separate the course particles of platinumbearing minerals and .
