The Mineral Potential Project currently being undertaken in British Columbia requires estimation d unknown mineral resources. The method of resource assessment known as the BC Mineral Resource Assessment Process [19931. is described by Kilby (1995, this volume) and in Grunsky et al. (1.994). The method is based on the three-part ssessment methodology developed by the United States Geologica...

With rapid development of advanced sensing technologies, rich and complex real-time profile data are available in many industrial processes such as steelforming manufacturing, chemical manufacturing, semiconductor manufacturing. These profile data provide valuable information about the quality or reliability performance of the process or product, and it is often desirable to utilize them to dev...

Early in World War II, a new map paper was developed that greatly improved the quality and performance of war maps. The National Bureau of Standards cooperated in the development and, subsequently, determined by experimental manufacture how to make the paper from commercially available raw materials. The best results were obtained in experimental manufacture by using fiber furnishes of 100-perc...

Controlling the plethora of fungal diseases common to our climate has always been an important part of growing grapes in New York and other Eastern regions. This has only become more important since I assumed the lead of Cornell’s grape pathology program in 1994. Major segments of the industry have shifted their focus to V. vinifera and interspecific hybrid varieties that typically are more dis...

With increasing international competition it is imperative that the South African sugar industry improves cane yields and quality, and curtails production costs. It is thus likely that increasing domestic labour costs will result in the long-run substitution of capital for labour (i.e. increased mechanisation). Given the high cost and indivisible (or lumpy) nature of mechanical inputs, it is im...

In the whole process of cement production, electricity consumption a raw material mill accounts for about 24% total. Based on statistics system 1005 production lines in China between 2014 and 2019, it is found that average preparation all clinker 2019 was 25.2 kWh/t. The different-tonnage varies with time. comparison high-tonnage ones, low-tonnage has wider distribution. dropped from 30.88 kWh/...

I N much of the Northern Great Plains area native grasses are of paramount importance to livestock production and hays from these grasses constitute the chief roughage harvested to maintain livestock when grazing will not support them. Tonnage of prairie hay harvested in South Dakota in 1948 and 1949, a total of 4,492,000 tons, was twice as great as the harvested tonnage of all tame hays combin...

1. Abstract A simulation analysis of a new method to identify a raw coal separation process to produce concentrate, middle product and refuse is presented in the paper. The washability characteristic of a raw coal, the partition curve of a gravitational separator and separation densities have been identified. The washability characteristic determines the yield and ash content (or other quality ...
