Abstract The research on the state of water ecosystems is significant in terms of future biological impacts of natural and anthropogenic effects. The key branches of natural resources management in Eastern Transbaikalia (agriculture, hydraulic power industry) are based on using water resources. The findings show that technogenesis affects surface waters of the region. Alluvial gold mining represents a significant part of mining industry. Gold mining in river channels results in run-of-stream diversion and interferes with the ecosystem of watercourses. A newly formed structure of a water ecosystem is not favourable for self-purification capacity of rivers. This leads to pollutants accumulation in water objects and deteriorates ecological state of watercourses. Natural components in the technoecosystem of hydropower objects in Eastern Transbaikalia are Lake Kenon and the Kharanor Reservoir. Although the catchment area is polluted by TPP-1, the ecosystem of the lake is still capable of self-purification due to biodiversity of hydrobionts. Under the dry climate in recent years, the Kharanor Reservoir ecosystem turned as rather unstable due to constant refilling from the Onon River. However, generally, pigment indices show physiological activity of primary producers of organic matter.

Main Activity

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.

AbstractDespite international protests against bonded labor, the flow of indentured laborers during the 19th and early decades of the 20th centuries was extensive compared to the earlier centuries. The focus of this article is on the particularity of the “Chinese coolies experiment” in South Africa's gold mining industry which commenced in 1904. This 20th-century episode of indentured labor is notable for several reasons, and it serves as a springboard for the discussion of some fundamental issues in capitalist development, labor and identity formation. This article emphasizes the last, examining how a “Chinese” identity was formed through the development of the gold fields and, in turn, how this formation reinforced a nascent white labor aristocracy. It discusses two dimensions of this labor “experiment” in South Africa: (1) the heady debate on the decision to look to China for cheap labor and (2) desertion by the indentured Chinese laborers from various mining compounds in the Witwatersrand.

Production Capacities

In Russia and abroad, the scope of the use of gold has significantly expanded, which undoubtedly affected the level of production. However, despite the fairly high rates of gold mining, the economic situation that has developed in recent years makes the companies look for new innovative placer processing technologies that will allow preserving and increasing the extraction of the precious metals. The search for and exploration of new placer gold deposits requires very considerable financial resources and time, and therefore the proposed project for the extraction of alluvial gold from technogenic deposits is of great importance for the functioning of the mining industry of the Irkutsk region, since it helps to overcome at least two negative trends: firstly, the deterioration of the mineral resource base, and secondly, large losses of gold with dump products (up to 50%) associated with the use of obsolete washing equipment. Modernization of production capacities and processing technologies is not only one of the main factors for increasing competitiveness in the gold mining industry and attracting investors, but will also help increasing the mineral resource base of the Irkutsk region by reassessing technogenic deposits, setting gold technogenic deposits on the balance, development of technologies for technogenic deposits and processing, and involvement of technogenic deposits in the mass processing.
