H.G. Miller, in Encyclopedia of Forest Sciences, 2004 Historical Background While the benefits of applying manure to land has long been appreciated the idea of a plant nutrients probably only dates from 1727 when Stephen Hale noted that ‘we find by chemical analysis of vegetables, that their...
Minerals with poor reducibility like hercynite and brownmillerite and with large-grained particles like free alumina and silica form in sinters with basicity of 2.4 and Al 2 O 3 content of 4wt.%, respectively. The appearance of these minerals can well explain the reduction stagnation phenomenon...
In the process of the present invention, the combustion adjuvant is applied directly and substantially solely to the coal particles that are increasing or causing the slag problem. The effective level of adjuvant required is thus drastically reduced. For instance if a level of 2 pounds of adjuvant...

PURPOSE: To prevent the elusion of hexa-valent Cr from the slag after the slag-off in separating or removing the slag produced in the melting and refining process of Cr steel from the surface of the molten steel. CONSTITUTION: The desulphurization distribution ratio (S)/[S] between the molte...
LF slag, or refining slag, is a basic slag produced in the final stages of steelmaking, when the steel is desulfurized in the transport ladle, during what is generally known as the secondary metallurgy process. From: Sustainable and Nonconventional Construction Materials using Inorganic Bonded Fiber...
These results are the first tangible evidence of a smelting process of tin ores in the entire region and therefore add a new dimension to the findings from previous mining archaeological investigations. At the same time, the results give significant information about the smelting process of ...

Tailings, which constitute a large proportion of the mining waste, originate from crushing and grinding processes used to extract valuable elements. Landfill mining material was used to produce blocks and bricks (Collins and Miller, 1979). More recently, material from recycling interventions and ...
