Copper Bioleaching in Chile

Chile has a great tradition of producing and exporting copper. Over the last several decades, it has become the first producer on an international level. Its copper reserves are also the most important on the planet. However, after years of mineral exploitation, the ease of extracting copper oxides and ore copper content has diminished. To keep the production level high, the introduction of new...

Low Complexity Modelling and Parameter Estimation in Copper Bioleaching Processes

Abstract: In heap bioleaching, metal is dissolved from ore by a percolating solution, catalysed by naturally occurring bacteria. Increased interest in the technology motivated the development of accurate models of such process in recent years. In contrast, the utilisation of such models for control has received limited attention, given their high mathematical complexity. This paper presents a l...

Prospect of Natural Gas Utilization in China

This paper introduces the source and utility circumstance of natural gas in China. The utility circumstance of natural gas is discussed in detail, such as, natural gas as feedstock is produced to acetylene; natural gas is used to cut metal; natural gas is applied to generate ethylene; natural gas instead of heavy oil is fired to produce chromium trioxide. In so doing, the energy demand of China...

Comparison of Copper Dissolution in Chalcopyrite Concentrate Bioleaching with Acidianus Brierleyi in Different Initial pH Values

Although bioleaching of chalcopyrite by thermophilic microorganisms enhances the rate of copper recovery, a high temperature accelerates iron precipitation as jarosite, which can bring many operational problems in the industrial processes. In this research work, the bioleaching of chalcopyrite concentrate by the thermophilic Acidianus brierleyi was studied, and the microbial grow...
