  • Conservation of iron and lime bearing raw materials by recycling of basic oxygen furnace (BOF) sludge in iron ore sintering

    Basic Oxygen Furnace (BOF) sludge is one of the by–products generated during process of steel making. It has very high level of iron oxide and lime content. However, the high moisture content of the BOF sludge (35–40%) is a major obstacle in its recycling. Internal recycling of the BOF sludge, with or without pre–treatment, is an integral feature of integrated steel plants in advanced countries. ...

  • Compacted lateritic soil treated with blast furnace slag as hydraulic barriers in waste containment systems

    Laboratory testing was conducted to assess the feasibility of using lateritic soil mixed with up to 15% blast furnace slag (BFS) by dry weight of soil as a suitable hydraulic barrier. Tests were carried out on the lateritic soil-slag mixture to ascertain the particle size distribution, index properties and compaction characteristics. The relationship between hydraulic conductivity, unconfined ...

  • Release behaviour of chromium from ferrochrome slag

    Huge amount of ferrochrome slag, a solid waste is being generated from submerged electric arc furnace during manufacturing of ferrochrome alloy. The waste slag contains about 6–12% chromium as chromium oxide and it has the potentiality of releasing hazardous chromium compounds. Although chromium exists in the slag as highly immobile Cr (III) state, there is possibility of chromium release under ...

  • The application of direct smelting of gold concentrates as an alternative to mercury amalgamation in small-scale gold mining operations in Ghana

    Mercury is used in small-scale mining to amalgamate gold particles, facilitating their separation from heavy sands. The negative environmental/health-related effects of mercury in mining communities in Ghana and other countries have generated research interest into development of safer alternatives. This study tested direct smelting as an alternative to amalgamation. In laboratory investigations, ...

  • Co-firing Solid Recovered Fuels (SRFs) with brown coal in large-scale pulverised fuel power plants – a simulation approach

    The results of the numerical simulations performed in a pulverised fuel boiler co-firing coal and Solid Recovered Fuels (SRFs) are presented. SRFs are initially modelled as a mixture of two different fractions (biogenic and plastic) and further simplifications are proposed to save computational expenses. The SRF submodels are validated with available data obtained from a laboratory-scale ...

  • Pharmaceutical glass manufacturer blends 120 batches/day of abrasive ingredients

    The manufacture of high-quality pharmaceutical glass is an exacting business that calls for careful control at all stages of the process in order to obtain the desired properties in the final product. Those properties vary, depending on what the glass is to be used for, so the initial step - the precise measurement and thorough mixing of multiple ingredients - is critical to the rest of the ...

  • Heat treatment of steels and other metals case study

    Application Moisture is measured in the blanketing gases that are used in the treatment of steel. Problem Inert blanketing gases are required during the heat treatment of steels to prevent oxidation of the metal product. At heat-treating temperatures, moisture and oxygen will readily react with the metal to form an undesirable metal-oxide coating on the ...

  • TOC analyser improves lab efficiency

    Leading instrumentation company HACH LANGE is helping a number of key customers save valuable time and costs with its new IL550 TOC-TN analyser. TOC analysis is vitally important in applications ranging from power generation, wastewater, drinking water, surface water and ultrapure water, to agricultural soils, contaminated land and food. HACH LANGE analysers therefore offer a range of options ...


  • Instant Loss on Ignition Results for Trommel Fines

    Cost-effective compliance with landfill tax regimes Many issues have been raised with HMRC’s proposed Loss on Ignition (LOI) testing regime for landfill taxes, including concerns that tests will take too long to be actionable and will cost too much to perform with any regularity. This may indeed be true for samples sent to a laboratory, but there is an alternative: the ...

  • Real-time TOC tightens effluent control at Greencore

    A food manufacturing facility in Selby has installed a new continuous TOC (Total Organic Carbon) monitor, ‘the BioTector’ which has dramatically improved the site’s capability to refine and improve the plant’s wastewater treatment process. As a result the plant is better able to quickly respond to changes in the influent. Greencore Foods is a leading player in the food ...


  • EnviroVantage-experts in asbestos abatement

    Asbestos is a group of naturally occurring minerals with long, thin fibrous crystals. It was sometimes referred to as the 'miracle mineral' because of its beneficial properties such as insulation and fire protection. In the U.S., chrysotile has been the type of asbestos used most commonly. Its long fibers are often found in a wide variety of materials such as vinyl floor tiles, mastic, sheetrock, ...

  • Asbestos in cigarettes

    The original version of the Kent Micronite cigarette filter used crocidolite, a form of asbestos, from 1952 until at least mid-1956. Cigarettes from intact, unopened packs of the brand from this period were examined. One filter contained approximately 10 mg of crocidolite. Crocidolite structures were found in the mainstream smoke from the first two puffs of each cigarette smoked. At the observed ...
