Allmineral is recognized worldwide as an expert in beneficiation of gravel, sand, coal and ore. Our machines and processes make intelligent use of physics and the forces of air and water. Our alljig®, allair®, and allflux®, machines have successfully been in operation for years, making us the right partners for all applications of separation and beneficiation of gravel, sand, ores, hard coal, lignite and slag. Furthermore, due to our expertise in recycling and applied ecology, we are also specialists in rubble separation and the cleaning of contaminated soil.
Our alljigs® operate reliably and economically. The feed material is fluidized by means of pulsating water. The particles stratify according to their density while specifically heavy grains settle to the lower level of the jig. alljig® jigging machines are designed for throughput rates of 5t/h to 700t/h per machine. Size ranges from 150mm to less than 1mm are efficiently separated, concentrated and cleaned.
The alljig® jigging machine efficiently separates all types of primary and secondary materials with different densities: gravel, coal, ore, slag, sand, crushed stones and different recycling materials. In addition, the system is easy to operate and maintain, and has very low energy and investment costs. More than 300 alljigs® represent a superb reference. This is underpinned by the world’s largest plant: the new 4,000t/hr iron ore processing plant of the Sishen expansion projects by Kumba Resources Ltd. in South Africa which uses 24 alljigs®.
The allair® jig contains many features of the alljig® wet jigging machine but works with air only. Especially for coal producers the allair®-jig is an innovation with regard to productivity and quality. The possibility of reducing ash and sulfur content without the pick-up of moisture in the process contributes both to the best possible exploitation of natural resources and to significant profitability increases.
The gaustec magnetic separator is mainly of interest for those customers who need to separate ferriferous (ie:magnetic) contaminations from vitreous and industrial sand. This unit is also ideal for sorting very fine particles, including inter grown ores and minerals according to their respective magnetic properties.
The characteristics of the gaustec high-intensity magnetic separator include the advanced separation efficiency and its enormous flexibility. The machine separates paramagnetic and low magnetic minerals of up to 3mm particle size in a wet separation process with magnetic field strengths of up to 15,000 Gauss. The main area of application is the enrichment of hematite iron ores as well as the extraction of heavy mineral sands and the separation of impurities with throughput rates of between 6t/h and 200t/h.
The allflux® process makes use of physical laws in a very intelligent way. The allflux separator uses fluidized bed technology for the separation and hydraulic classification of slurried fines - separating light products from fine materials like sand. The two-step process permits the handling of slurries without pre-thickening.
This leads to high efficiency and high capacity. Throughput rates of up to 2000m³/h in a single unit can be realized. Particle size up to 4mm can be treated. The advantages of the allflux are recognized worldwide. Classifying, separating, thickening and desliming in one step – a convincing process. Applications for the allflux technology include sand, coal, ore and mineral sand.
