Metals recovery from industrial wastewaters and metallic hydroxide sludges through microbial sulphate-reduction.
This paper describes how metals originate in industrial wastewaters from the mining and metal finishing industries. Treatment of wastewaters containing dissolved metals produces a metallic hydroxide sludge which has to be disposed of in an environmentally acceptable way. It is estimated that the …

A one-step ambient temperature ferrite process for treatment of acid mine drainage waters
… low in pH, very high in dissolved iron, high in non-ferrous (mainly heavy) metals and very high in sulphate salinity. As such, AMD waters present a serious environmental problem in the mining regions of South Africa and elsewhere in the world. Treatment of AMD therefore requires pH …

State, Resources and the Development of Modern Manufacturing in Zambia, 1924-1973
… output of Zambia failed to include the output of non-ferrous metals processing; thus, many studies have underestimated the level of modern manufacturing during the colonial period and the first decade following Zambia’s independence from Britain. The dissertation, therefore, argues that the modern …

Modeling of Eddy Current Separation
Eddy current separation aims to recover non-ferrous metals from non-metals utilizing electromagnetic interactions. In order to describe the separation process, a representative model is needed that can accurately calculate the induced forces. Such a model can be used to optimize the efficiency of …

Renewable Energy in Industrial Applications
… of energy-intensive commodities such as ferrous and non-ferrous metals, chemicals and petrochemicals, non-metallic mineral materials, and pulp and paper. In these sectors, energy costs constitute a large proportion of total production costs, so managers pay particular attention to driving …

Solid state diffusion bonded damascus steel and its role within custom knifemaking.
… technology to an ancient process of laminating metals for blades and explored the application of the new possibilities to a craft context. This research built on work by Ferguson on solid-state diffusion bonded Mokume Gane by moving from metal combinations suitable for vessel-making to metal …

The detection and identification of extraneous metals in material conveyance systems
… design and build an equipment which can detect ferrous and non-ferrous objects in conveyed commodities, discriminate between them and locate the object along the belt and on the width of the belt. The magnetic induction mechanism was used as a means of achieving the objectives of this research. …

Analysis of barriers and success factors affecting the adoption of sustainable management of municipal solid waste in Abuja, Nigeria
… of MSW samples from the City comprises mostly of non-degradable but recyclable materials such as glass, metals and cans, non-ferrous metals and waste electrical and electronic equipment. The implication of the high levels of moisture content in the biodegradable components is that samples are not …

On the selective flotation of pentlandite from pyrrhotite in Sheba's Ridge ores
… raw material for most of the world's supplies of non-ferrous metals and can be considered one of the most important group of ore minerals. In the context of South Africa, the Bushveld Igneous Complex (BIC) sulphides play a very important role in that they are largely associated with the valuable …

Temporal Issues in Market Inefficiency in asset prices with an emphasis on commodities
… The methodology is empirically applied to non-ferrous metals with particular attention to Copper; we believe this is an additional contribution of the article. Chapter 3 also presents a partial equilibrium model which leads to an estimable reduced form expression for commodities and thereby …
