Rio Tinto Alcan

(formerly Comalco Aluminum)

Major jointly developed the Automated Siphoning System with the then Comalco and is licensed to manufacture and sell worldwide these systems for delivering molten metal into furnaces.

Rio Tinto Alcan who manage primary aluminum smelters at Boyne Island and Bell Bay Australia and Tiwai Point, New Zealand together with Major jointly developed the Siphon Pipe Handling Systems, its structure and its Control System.

Tests with the fully operational system showed a reduction of some 75% of Dross make due to the enhanced, non turbulent flow achieved throughout hot metal transfer, thereby reducing scrap metal sent to recycling or secondary processing.

Vortexer

Unique system to submerge UBC’s and fragmented scrap – dramatically improves yield by putting the feed material quickly below the surface of the molten aluminium, providing rapid melt rates and greatly reduced dross formation.

Vibratory Conveyor Feeder

ROMJIG®

Moveable sieve jig for primary separation of refuse from the coarse raw coal. By means of a moveable screen rocker arm the grains are loosened and stratified. Coarse coal can thus be separated in a light and a heavy fraction at low specific operating costs and with high efficiency.

Feed size 30-400mm

Throughput rates max. 400t/h

BATAC®JIG

Jig for processing all kinds of coal, iron ores, ferroalloy slags as well as many other different minerals.

Feed size 0-150mm

Throughput rates 30-1000t/h

Effective jigging widths 1-8m

The main advantages of BATAC Jigs compared to conventional jigs and heavy-medium plants (HMS): higher efficiency, huge economical benefits, better product quality, better machine availability and higher throughput rates.

TESKA Heavy Media Separators

Dense media separation of coal and ores is performed in a suspension of finely ground solids and water.

The TESKA Separator is a slowly rotating bucketwheel joined to feed and discharge compartments by seals. Adjustable nozzles arranged around bucketwheel perimeter induce downward flow of heavy media and therefore preventing undesired density concentrations.

PNEUFLOT®

Pneumatic flotation for beneficiation of coal and minerals.

Solids Feed size <0.5mm

Throughput rates max. 600t/h dry solids for each machine

Pulp throughput max. 1200m3/h

Since introduction to the market in 1995, over 100 PNEUFLOTs have been installed in the fields of coal, industrial minerals, ores and secondary raw materials. PNEUFLOT imporves product purity and yields. Low investment and operating cost, low wear and high efficiencies are further characteristics of PNEUFLOT in comparison to conventional flotation cells.

JONES®WHIMS

Wet High-Intensity Magnetic Separator (WHIMS) for processing of low magnetic susceptible ores, feebly magnetic minerals from non-magnetic particles by a wet process even to very fine sizes.

Solids Feed size <1mm

Throughput rates 0.5-200t/h

JONES WHIMS enables very high magnetic fields at low current consumption but also yields high throughput rates in a compact machine.

PERMOS® MIMS

Medium-Intensity Magnetic Separator (MIMS) for dry and wet separation of ferromagnetic and paramagnetic ores and minerals.

Solids Feed size <5mm

Throughput rates max. 100t/h

PERMOS MIMS with a wide working range outside the drum allows a dry and wet magnetic separation of coarse and fine minerals, particularly high grade ores of medium susceptibility at high throughput rates. The PERMOS operates at field intensities around 0.5 Tesla on the drum surface and meets the demand for cost-effective solutions for many applications which are outside the scope of traditional low intensity permanent magnetic separators that reach only up to 0.2 Tesla on the drum surface.

PALLA®

Feed size 0-15mm <max. 0-30mm)

Grinding fineness <10um 9in airclassifier <3um)
