111 We present a computable general equilibrium model of the interface between the Great Salt Lake (GSL) ecosystem and the regional economy that impacts the ecosystem. With respect to the ecosystem, the model treats the various representative species as net-energy maximizers and bases population dynamics on the period-by-period sizes of surplus net energy. Energy markets-where predators and pre...

Nutritional minerals have been sourced from the Great Salt Lake (GSL) and provided to domestic and international markets since 1969. Endorheic properties of the lake leading to high mineral concentrations, in conjunction with the vastness of the lake, set the GSL apart as the most logical location for nutritional mineral extraction in the world. In spite of the vast abundance of mineral-based r...

Deep sea mining tailings disposal is a new environmental challenge related to water pollution, mineral crust waste handling, and ocean biology. The objective of this paper is to propose a new tailings disposal procedure for the deep sea mining industry. Through comparisons of the tailings disposal methods which exist in on-land mining and the coastal mining fields, a new tailings disposal proce...

Although mule spinning has been used in the cotton and wool industries for about two centuries, the *earliest recorded cases of mule spinners' cancer were not reported until the end of the nineteenth century. From then on the number of cases rapidly increased. Evidence accumulated which strongly suggested that the mineral oil used to lubricate the mule spindles was the cause. It is remarkable t...

rajasthan is one of the main mineral potential state of india. during the last 30 years it has witnessed enormous expansion of mining industries, but mining of most of the minor minerals coupled with changing climate has posed serious problems to the environmental fabric in the state, apart from base metal beneficiation plants. groundwater is also being polluted day-by-day by effluents generate...

The history of the mining industry is intimately connected with government regulation. As in many other countries, this reflects the fact that the Crown has reserved almost all mineral rights to itself. In many cases regulation has had adverse consequences for the sector. A notorious example was the ban on exports of iron ore in the 1960s, which depressed exploration activity and postponed the ...

The 15th Annual Conference of the Mineral Economics and Management Society will take place in Golden Colorado, April 19 -21, 2006. This year’s theme focuses on one of the most critical issues facing mining and minerals – the issue of energy. Entitled “Mining Energy Outlook: Economic Barriers and Solutions to Energy Issues in Mining”, the conference will look at energy through three lenses impor...

Self-consolidating concrete (SCC) is becoming a popular choice in concrete industry due to ease of placement in congested reinforcements, reduced labor and equipment, nonsegregating character, and smooth surface. Due to its sensitivity to aggregate grading, proportions, admixtures, and filler contents and being a relatively new material, more information are required on the effects of aggregate...
