The World Gold Council and its member companies support the responsible mining and trading of gold from all legitimate sources, including artisanal and small-scale mining (ASM). The responsible development of gold resources both through large-scale mining (LSM) and ASM, especially when coupled with sound governance, has the potential to deliver broad social and economic benefits to individuals, communities and countries. There has been a significant growth in artisanal and smallscale mining in many developing countries over the last twenty years. ASM issues have become more salient in public policy debates as a result of the adoption of instruments designed to prevent the funding of illegal armed groups and from the implementation on reducing mercury in the environment. Artisanal and small-scale mining is more than simply an industry with the potential to contribute positively to foreign exchange earnings and employment; it is a way of life. Its participants, most of whom were lured into work by the prospect of gaining wealth quickly, include rural community dwellers, nomadic peoples, seasonal subsistence farmers, and retrenched largescale mine workers. However, despite providing higher wages than comparative rural sectors of industry, artisanal and small-scale mining is generally associated with a deteriorated quality-of life KEYWORDS Small-scale gold mining, explosive, gold mining, well spacing, rock, rock mass, blasting, rock strength, open pit mining, parallel-close charges.

The introduction of the method of chemical trapping of nitrogen oxides in a complex with selective catalytic purification of tail gases from industrial production makes it possible to increase the service life of the catalyst regardless of the NOx concentration, create a cycle of low-waste technology and achieve significant savings in the consumption of the scarce AVK-10 catalyst ... Reuse of the spent catalyst AVK-10 in the process of cleaning tail gases of industrial production from NOx and absorption-catalytic cleaning of the latter with the use of solid waste products allows simultaneously solving environmental and economic problems in the production of weak nitric acid. The prospect of using the waste of lead-concentrating factories as a natural sorbent-catalyst in gemological is substantiated. processes of purification of waste gases of sulfuric acid production. The proposed chemisorption-catalytic method for purifying waste gas mixtures from sulfur dioxide does not require special preparation of a wet, high-temperature dusty gas. The use of natural materials within the framework of this method allows you to extract from them valuable raw materials-metal oxides.
