Mining & minerals solutions for coal preparation industry

by WesTech Engineering, Inc.     based in Salt Lake City, UTAH (USA)

WesTech designs and manufactures thickeners for the coal prep industry for product concentration, tailings disposal and CCD circuit washing, including HiFlo Thickeners and Deep Bed Paste Thickeners. Paste thickening is a proven technology increasing the profitability of mining operations. In the coal preparation plant there are two applications for paste thickening: concentrating fine coal and producing paste from coal tailings for increased water recovery and elimination of tailings ponding. Paste thickeners recover the maximum water possible from tailings streams. Tailings disposal sites have a longer life and the land can be reclaimed faster and easier. New tailings disposal sites can be smaller and significantly less costly.

Continuous Gravimetric Feeding for Coal Mining Industry

by Schenck Process Germany     based in Sandnes, NORWAY

Applications in coal mining, the processing of non-ferrous metals, costeaning and preparation in mines require technology and materials capable of withstanding the most extreme conditions. Schenck Process solutions prevail where others give up. Our products are durable, indestructible and extremely reliable under the most difficult conditions.

Whether large lumps or the finest fragment, wet or dry and irrespective of whether using ore, scrap, lime powder or hot sinter up to 1,000 °C – vibratory equipment supplied by Schenck Process can deal with all types of bulk materials. Every year around 10 million tonnes of raw coal are freed of impurities with the help of our coal washing plants – which represents our contribution to environmentally friendly energy production.

Our customised application solutions include both heavy-duty and static weighing technology, conveying, screening, drying & cooling and dewatering. From planning and design through to the construction of the plant sections, reliable controls and connection to data systems.

GIS software for mining industry

by Esri     based in Redlands, CALIFORNIA (USA)

The resources in the earth`s crust require sophisticated technology to discover, extract, and manage. Since mining is inherently spatial, requiring accurate knowledge of areas of the earth`s surface and subsurface, geospatial technology is best suited to intelligently oversee all phases of the mine operation. GIS gives mining companies the tools they need to operate mines responsibly and at optimum efficiency. It is a comprehensive, interoperable technology specifically designed to compile, process, display, analyze, and archive volumes of interdisciplinary data.

Mixers, dryers, innovative solutions for power plant technology

by AVA - Huep GmbH u. Co. KG     based in Herrsching, GERMANY

Conditioning of Ash and Dust

No matter where ash and dust accumulate, AVA continuous or batch mixers can condition them to a transportable final product for disposal or recycling. The applications range from power plant ash derived from lignite, hard coal, biomass, or waste incineration power plants to filter dusts from steelworks and coking plants through to special applications such as hot or reactive ashes from various processes, such as shale oil production.

Power Generation

by Babcock & Wilcox MEGTEC     based in De Pere, WISCONSIN (USA)

MEGTEC is actively involved in providing Power Generation solutions for many applications ranging from utilizing process heat recovery systems to utilization with boilers, to recovering and utilizing Ventilation Air Methane (VAM) from coal mines. MEGTEC has developed VAM processing technologies for either abatement only and in combination with energy recovery and utilization. MEGTEC’s proven technologies are destroying methane while generating high quality carbon credits, electricity for coal mines and heating for local communities and facilities.

Air pollution control for ventilation air methane industry

by Anguil Environmental Systems, Inc.     based in Milwaukee, WISCONSIN (USA)

Ventilation Air Methane (VAM) is a Greenhouse Gas (GHG) released by coal or mineral mining operations, it is also commonly known as Coal Mine Methane (CMM).  The air pollutants from this process have a global warming potential 21 times greater than carbon dioxide, which is another well known GHG.  As alternative energy technologies have developed, methane is increasingly used to generate electricity and heat.  Landfills and mines represent two of the most abundant sources, however reports indicate that more than 50% of all VAM is exhausted from mine ventilation systems and remains unutilized.

Application package Ash for analysing oxidic materials

by Fluxana GmbH Co. KG     based in Bedburg-Hau, GERMANY

This application package is a `ready to go` calibration kit for xrf instruments. Fusion technology is ideal for analysing oxidic materials like ashes. It performs with the highest precision possible in xrf sample preparation. Primarily power stations and their control laboratories have to check the ash from the burning process of black and brown coal. Two standard DIN and ASTM methods describe the testing in detail. FLUXANA is able to deliver both methods ready from the bench.

Water treatment for power plants

by De Nora Water Technologies     based in Colmar, PENNSYLVANIA (USA)

The process of electricity generation from fossil fuels such as coal, oil and natural gas is water-intensive. Between 40-50% of all water abstracted and used in developed countries is used in the generation of electricity. Thus, a reliable, abundant and predictable source of raw water supply to a power plant is a critical factor in site selection. Water supplies are required to provide various process waters for the following essential main purposes such as make-up water, cooling water for steam turbine condensers, and auxiliary plant cooling water.

The primary application of modern water treatment technology is to maintain the integrity and performance of the power plant. Critical plant applications have water purity or conditioning requirements that must be adhered to for safe, reliable and efficient power generation.

Experience has shown that integration of water technology treatments with power plant design can be very important in reducing operational problems and component failures 

At power plant worldwide there are increasing limitations on water availability and environmental restrictions on discharges. This is expected to promote measures for water conservation and to have an increasing influence on water treatment decisions. At power plant, the recycling of internal wastewater streams can extend from the recovery of individual high-quality waste streams, which can be reused either directly or after only limited treatment, through to the development of fully integrated water/wastewater treatment systems for zero liquid discharge. However, the application of reuse schemes requires site-specific assessment, as not all waters may be viable options for recovery.
