This paper presents the key features of an engineering methodology dedicated to Organisation Networks. This methodology constitutes one of the elements of a full engineering framework developed through a PhD research thesis. The authors mainly focus hereafter on specifying the “design” and “preliminary engineering” activities of the engineering procedure. The methodology is illustrated on a cas...

Metallurgical accounting in the mineral processing industry transforms accumulated process data, including flow rates and assays, into a coherent information format. This is used to rapidly provide production reporting and key performance indications. Comprehensive and coherent data must be a component of any system expected to accomplish reconciliation in the mass-balancing process. Quality is...

‘Wire bonding’ is used throughout the microelectronics industry for interconnecting dice, substrates and output pins. Fine wires, generally of aluminium or gold 18–50μm in diameter, are attached using pressure and ultrasonic energy to form metallurgical bonds. Devices bonded with gold wire generally need additional thermal energy, and the bonding process is referred to as ‘thermosonic’ rather t...

processing of minerals and production of metals has increased greatly in recent years. as a result, the quantities of waste material and pollutants have also increased. in many cases technology has changed to cope with the problem. processes have been either modified to decrease emissions, or replaced by others that are less polluting even if at a higher cost. this paper briefly reviews example...

Recycling of by-products of the steelmaking process in electric arc (EAF) furnaces is an important activity from the perspective of environmental protection as well as the steelmaking industry itself. This article is a discussion concerning the selected research results in terms of utilisation of steelmaking dusts containing 4 12 % of zinc in manufacture of cement bricks, ceramic construction m...
