An input–output analysis of the impact of mining on

We use input–output techniques to analyse the impacts of gold, coal, and other mining activities upon the South African economy between 1971 and 1993. Our results suggest that the premise upon which the South African government's proposed minerals policy is based, i.e. that “the mining industries have the capacity to generate wealth and

4 Coal Mining and Processing Coal: Research and

2021-2-1  Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique

Operational Objectives and the Transformation

These can be considered as support processes in the operations hierarchy (Greasley 1999). The key output of the key process (via turbine/generator) is electricity. Outputs products and services are usually classified by their tangibility (Greasley 1999). For

Refining crude oil inputs and outputs U.S. Energy

Refining output is larger than input. The total volume of products refineries produce (output) is greater than the volume of crude oil that refineries process (input) because most of the products they make have a lower density than the crude oil they process. This increase in volume is called processing gain. The average processing gain at U.S
