Diamonds
Overview
Consulmet's core expertise lies in diamond processing and recovery for alluvial, kimberlite and lamproite deposits. We design, build and operate complete diamond processing plants for major diamond producers, including Rio Tinto, Gem Diamonds, and Lucapa Diamonds. Consulmet has designed and built complete diamond plants ranging in capacity from 1,500 tph down to small, skid-mounted bulk sampling plants.
Our plants utilise our range of in-house designed and built diamond processing modules and circuits, which include:
XRT (X-ray transmission) modules
Dense Media Separation (DMS) modules
Crushing, milling and scrubbing circuits
Our innovative wet-front-end solution for high-clay ores
Final recovery (X-ray, grease and final sorting) circuits.
Case Studies
Flowsheet Design & Simulation
Our team are expert in all aspects of diamond processing, from crushing and feed preparation to final recovery. As part of every Consulmet diamond processing plant, we complete a full flowsheet simulation to optimise diamond liberation and recoveries across all targeted stone sizes.
Crushing, Milling & Scrubbing
The correct selection and design of crushing, milling and scrubbing circuits are essential to diamond liberation for kimberlite and lamproite ores. Equipment must be carefully integrated into the project flowsheet to maximise plant throughput whilst preventing the breakage and loss of large diamonds. We have vast experience in the design and operation of:
autogenous mills;
hybrid and HPGR crushers; and
log washers and conventional scrubbers for high-clay ores.
We have developed a proprietary wet-front-end solution for handling sticky, high-clay ores. Our highest capacity front-end circuit to date is a 1,500 tph milling circuit for an Angolan diamond mine.
Consulmet works with industry-leading equipment vendors to simulate and specify the best feed preparation flowsheet to optimise diamond recoveries. We can also integrate our XRT modules into the circuit to maximise the recovery of large stones and reduce the possibility of diamond damage.
150 tph primary crushing circuit & 100 tph autogenous mill for Gem Diamonds
Consulmet pioneered using XRT machines in full-scale production diamond plants in 2012. Since then, we have designed and built dozens of XRT Recovery Plants.
We also offer a modularised solution for the recovery of large diamonds.
70 tph modularised XRT plant
We built our first diamond DMS module in 2006. Since then, Consulmet has designed, built and operated dozens of DMS modules and plants for major diamond producers, including Rio Tinto, De Beers, Gem Diamonds, Namakwa Diamonds, and Lucapa Diamonds.
We also offer a full range of in-house designed and built diamond DMS modules for both lumps (coarse) and fines for tonnages from 2 tph to 250 tph.
Final Recovery
Consulmet designs, builds, and operates final recovery houses incorporating X-ray machines, grease belts and glove boxes. We also design and install state-of-the-art security systems.
Bulk Sampling & Pilot Plants
Consulmet offers a pre-engineered range of trailer and skid-mounted bulk sampling and pilot plants, including XRT, DMS, crushing and scrubbing units.
10 tph trailer-mounted bulk sampling plant
30 tph trailer-mounted bulk sampling plant (for BHP)
Skid-mounted bulk sampling plant (for Rio Tinto, Canada)
