BATEMAN has supplied a jigging plant to Xstrata SA (Pty) Ltd in Lydenburg, Mpumalanga, SA. The plant is designed to treat 150 t/h of ferrochrome slag.
 


The Xstrata jigging and spirals plant in Lydenburg,
RSA– a new concept design by BATEMAN.

Hendrik de Beer, Services and Logistics Manager at Xstrata , the driving force behind this metal-recovery plant, explained that its expected metal yield is between 2 and 2,5 %. "Even at this low head grade, the project is still regarded as extremely viable," said de Beer.

The plant consists of a coarse Apic jig with a design capacity of 90 t/h and a fines Apic jig of 45 t/h. The Apic jigs are in-house BATEMAN technology. A 15 t/h spirals section is fitted with four-stage spirals, rougher, cleaner, re-cleaner and scavenger spirals – to collect the very fine material. Water reticulation and slimes handling circuits are also provided. A Bateman Ultrasep thickener is used or slimes concentration and the slimes are pumped to an existing Xstrata slimes dam.

This metal-recovery facility is a new BATEMAN design concept. The plant is designed to incorporate the spirals with minimal slurry-pumping and process control. A 1 000 tonne buffer stockpile has been established between the crushing plant and the metal-recovery plant.

The contract was signed in January, construction started in April and hot commissioning completed t the end of August, successfully meeting its design performance. This turnkey plant was built on a hared-savings basis, completed on time and under budget, with the savings shared by client and contractor.
