Essays on Smelting

Introduction

Natural resources for decades have always provided many nations with the affluent source of wealth that helps in building their economy. As such, many of the countries that majorly depend on the natural resources such as copper, oil, gold and uranium often embark on intensive mining practices to ensure their natural reserves are productive and can offer sustainability to their economies. Due to their dependency on these resources, the countries often have structures and laws that govern how they handle the resources in every stage to ensure maximization. It is important to highlight that the resources are most often ...

Extraction Stage

Extraction of copper produces both specks of dust and gaseous wastes such as sulfur dioxide and carbon dioxide that significantly contribute to environmental pollutions, especially air pollution (“Copper Mining”). Whereas copper wire miners reduce this pollution level by trapping the generated sulfur dioxide gas for purposes of producing sulfuric acid, considerable amounts of sulfur dioxide still escape and take part in both air and water pollution. However, extraction methods that incorporate emulsion of liquid membranes and applications of microorganisms in removing copper from their underground ores have been currently established as the economical and viable ways of gathering copper. ...

This can lead to serious health hazards and create toxic footprints. The essay looks at new developing technologies for the recycling of computers and creates a report on the basis of the quadruple ...
