ROBERTS, MARK CULMER. "THEORY AND PRACTICE OF THE INTENSITY OF USE METHOD OF MINERAL CONSUMPTION FORECASTING (MINERAL, ECONOMICS)." Diss., The University of Arizona, 1985. http://hdl.handle.net/10150/187962.

Full text

Abstract:

The intensity of use of a mineral is traditionally defined as the consumption (production plus net imports) of the mineral divided by gross national product. It has been proposed that this ratio of raw material input to gross economic output is a predictable function of per capita income and that the relationship is based on economic theory. Though the theory has never been clearly defined, the intensity of use method has been used to make long term forecasts. This dissertation formulates a theoretical model of the consumption of minerals and the resulting intensity of use which is used to tes

Abstract:

Junior mining companies provide a vital feedstock to the mining sector, which in turn, feeds into the wider economy via manufacturing. The valuation models traditionally used in other sectors of the economy appear to be insufficient, in terms of scope and capacity to handle uncertainty, to provide a rational pricing of junior mining companies. The observation that junior mining firms are valued by some means suggests that either the junior mining markets are inefficient or, more likely, that these markets are able to provide insight, scope, and capacity to the methods of firm valuation.

Abstract:

Bristol Bay, in Southwest Alaska, is the largest sockeye salmon fishery in the world. After an almost total collapse of salmon numbers in the mid 1970s, the salmon have returned and average in the tens of millions every year. The salmon play a vital economic, cultural, and subsistence role in the lives of the people who call Bristol Bay home. At present there is a plan to develop a low-grade, but substantial, mineral deposit that consists primarily of copper, gold, and molybdenum. The estimated value of the minerals present is more than $500 billion. This plan is known as the Pebble Project, a

Abstract:

This study introduces a new methodology referred to as geoinformation synthesis for multivariate evaluation of mineral resources and integration of diverse geoscience data. The most critical component is the development of the notion of intrinsic samples and the methods for their delineation. Intrinsic samples replace grid cells which are conventionally employed as the basic information reference. Grid cell sampling has imposed several serious limitations on the geoscience and genetic information that can be objectively related to mineral endowment. Methods based upon intrinsic samples moderat

Abstract:

The thesis is concerned with a theoretical study of the flow behaviour of inelastic power law fluids in two different types of flow situation. These are: 1. The creeping motion of a sphere moving through an expanse of liquid. 2. The combined steady and oscillatory flow of a liquid through a straight tube of circular cross section. The first part of the work is devoted to the prediction of the drag correction factor for a sphere falling slowly through a bounded inelastic power law fluid. The analysis is carried out for the case when the outer spherical boundary has a finite or infinite radius.

Initially the sample positions were co-ordinated, then the geological, soil and sample types were allocated to each point. Twelve lithological groupings were chosen which incorporated most of the available data, retained significant geological characteristics and consisted of statistically significant

Abstract:

Cerro Rico is the world's largest silver deposit. Hypogene mineralisation is hosted by a sheeted, polymetallic vein system which cross-cuts a pervasively altered rhyodacite dome. The 13.8Ma dome was intruded along a regional dextral strike-slip fault. Subsequent movement focused stress within the dome, creating a closely-spaced fracture system, best described as an extensional duplex. Hydrothermal alteration shows features characteristic of both porphyry and epithermal deposits.

The study begins by investigating Thailand’s administration of its mineral resources and those of some other leading mineral-exporting countries for comparison. The notion of ‘resource curse’, which affects many resource-rich countries, and an analysis how Thailand fought and won the ‘curse’ is critically explored. The principle of sustainable development and its implication to Thailand are presented, together with various computed indicators of sustainable development for Thailand. The role of mineral resources and Hotelling’s model in the context of sustainable development are discussed. The

This thesis describes preliminary research on the application of Markov Decision Processes (MDPs) to the optimisation of mine scheduling in an uncertain environment. The MDP framework is a novel approach to scheduling in a mining operation and option valuation. The task of scheduling in mining operations is dependent on the availability of models that permit the representation of some of the key stochastic properties of the environment, such as grade and price uncertainty. The tools used to model these processes are respectively sequential Gaussian simulation and Geometric Brownian motion. Thr
