Abstract: In rural regions, mining is an activity that employs many people due to the fact that the barriers to entry are sometime trivial, with very low technology, capital fund and no specialized skills required. Many people including children into artisanal mining in Ivory Coast because they can earn higher incomes in mining than through other traditional activities such as agriculture, which is the main activity in the country. Artisanal mining contribute to reduce the abject poverty and it offers many others opportunities. However, this activity has many negative social impacts. Local people including miners are risking their life everyday due to the unsanitary conditions, prostitution, chemical contaminants, and alcoholism, and also the large degradation of lands. The main objective of this Paper is to understand how artisanal gold mining in the Ivory Coast affects local livelihoods and the environment. Some key recommendations for addressing artisanal mining activities in order to have a good option for sustainable management of mineral resources in the country are proposed.

Abstract: The need to reduce carbon emission in Heilongjiang Province of China is urgent challenge facing sustainable development. This paper aims to make explicit the problem-solving of carbon emission to find low carbon emission ways. According to domestic and foreign literatures on estimating and calculating carbon emissions and by integrating calculation methods of carbon emissions, it was not possible to consider all of the many contributions to carbon emissions. Calculation model of carbon emissions suitable to this paper is selected. The carbon emissions of energy consumption in mining industry are estimated and calculated from 2005 to 2012, and the characteristics of carbon emission are analyzed at the provincial level. It makes the point that carbon emissions of energy consumption in mining industry can be reduced when we attempt to alter energy consumption structure, adjust industrial structure and improve energy utilization efficiency.

Abstract: Mining industry is growing rapidly during the last few years. It shows that the use of explosives is a crucial part mining industry explosion and drilling costs take about 40% of all mining related expenditure. Cost effective explosion procurement and services will help mining industry to save time and money. This process demands the automation of the production of explosives with the goal to save time and manufacture safe and reliable products. This article provides an overview of creating an automated system design for emulsification by using technology of proportionally mixed liquid.

Abstract: Waste are the product, left behind, of the mines activity in Poland. Having in mind, that this kind activity is conducted on a large scale, because coal is still the main source for polish energetic sector, it generates a large amount of waste. Which needed be to treated appropriately. This waste management (waste from mines) is a major line of the enterprise, presented in this article. Like any other, in this company there are processes that altogether create a supply chain. However, due to the type of waste and taking account the present business condition, enterprise has implemented, recently, the elements into the logistics processes, which are consistent with sustainable development conception. These elements will be described in this article together with the effects of its use in economic, environmental and social aspects

Abstract: This study analyzes China’s coal industry by focusing on five related areas, namely, resource flow, coal consumption, carbon footprint, accidents and deaths and international opinions.

Abstract: Wastewater in mining and concentration operations is of high acidity, and contains a vast array of heavy metal ions, and some organic compounds. Biological treatment of the wastewater in some metallic-ore mines and concentrators are reviewed. There is a fast development of biological process from fundamental research to large scale commercial application in the past 20 years. Compared with other processes, biological process has an excellent performance without secondary pollution, including its wide pH application range, small investment and low operational cost. Biological process is still a promising process in treating wastewater for mining industry.

Abstract: Several studies and different successful commercial applications had demonstrated that bioleaching can be an innovative approach that is capable to provide mining industry opportunities for essential growth in the medium term[2-18]. To identify the commercial application potential of bioleaching in Iranian copper industry, a research program was initiated. The objective of the main part of this program was to evaluate bacterial leaching processes for copper recovery from (i) high grade ores and flotation concentrates and (ii) low grade ores and flotation tailings. The latest results of these studies indicates the general operability of the bioleaching in both cases. At optimum conditions, the copper extraction from low grade materials was more than 80% and that from high grade ores and flotation concentrates about 95%, which should be high enough to justify the process economically.
