The residual porosity is an unavoidable phenomenon of the components produced by powder metallurgy process which in turn largely affects the strength property of the same. Now a day it is possible to control porosity of powder metallurgy components and retain them to desired amount when required. The porosity of a powder metallurgy component is greatly depends on the sintering temperature. In t...

It is important to measure the burden surface temperature of blast furnace (BF) since it can indicate the gas flow distribution and provide instruction for BF operation. The measuring system configuration based on multi-source information fusion is given in this paper to solve the problem of temperature filed measuring in BF. As a result, the multi-source information feature extraction and fusi...

Mining and metallurgy have negative consequences for the environment [1-3] and lead to changes in geological [4] and climatic conditions [5]. Mining-metallurgy operations include the extraction, preparing of ores (crushing ore and flotation), processing of concentrates, and the disposal of waste rock and by-products. The main waste in mining and metallurgy are waste rocks, flotation tailings an...
