The research aims to work out in details the measures taken to limit ecological risks when producing ore in highland regions.
Research methodology includes applying the methods of X-ray fluorescence spectrometry, neutron activation analysis, and mass spectrometry to study the mechanism and indicators of environmental ecosystems chemical pollution with the products of synergetic interaction among the ingredients in metallic minerals.
Research results and scope. The data on the role of water in mining have been introduced. The features of mining industrial wastes impact in the conditions of the Caucasus highland. The leading role played by metallic ore mill tailings in chemical pollution of highlands has been numerically proved by the example of the major fields. The idea has been formulated that highland territories are weakened and public health is deteriorated due to chemical contamination of highland environment by mining waste. Quantitative parameters of mining and smelting impact on public health have been determined, and the prospects of measures taken to protect population from the negative impact of mining have been forecasted. It has been shown that overall protection of environment from chemical pollution is possible only in case of advanced recycling of waste. Advanced methods of trade effluent reclamation have been recommended. Research results may be applied at the underground development of metallic ore deposits.
Summary. In the conditions of highlands, ecosystems contamination with the products of synergetic interaction among the ingredients of metallic materials in the process of metal production increases. Environmental protection from chemical contamination with liquid products of mining is possible by extracting chemically dangerous metallic ingredients and reducing their concentration down to the level of hygienic standards with the use of new natural and resource saving technologies.

Key words: mining; trade effluent; ecology; mill tailings; ecosystem; public health.
