In article gold mining problems at deficiency of stable stocks, exhaustion of a source of raw materials and lack of scientific and technical progress in development of new technologies are stated. Resource potential of technogenic complexes of Russia is estimated at 50-60% of the metal extracted in the country. Over the last 50 years when developing scatterings the content of gold was reduced by 10 times(with 5 to 0,5 g/m3). Thus the high prices of energy carriers and growth of non-productive costs can’t compensate the even constantly growing prices of precious metals.At gold mining from loose fields, enrichment is carried out by easy gravitational ways mainly on lock devices of deep and small filling. Two-stadial enrichment or otsadochny technologies is less often used. Gold of fraction (-0,25 mm) is extracted by lock devices no more than for 5-10%, and production growth thus is provided due to accumulation of volumes and productivity (extensive growth). In this regard it is necessary to provide the theory of economic growth of the American economist of the Nobel Prize laureate of 1987 Robert Solou. In his opinion, investment into cars and the equipment, bigger use of natural, manpower reserves can’t be a source of economic growth on a long-term outlook. Technological changes, professional development of labor and the best organization of work can be the only source of intensive growth.The gravitational technology for an assessment and development of technogenic complexes of precious metals is offered. In JSC SEVER of the Republic of Sakha (Yakutia) it is created and semi- industrial concentrating installation - basic option (the Patent Russian Federation No. 2483807) passed tests. Unlike the existing devices and technological schemes, the declared technology has the distinctive features:allows to extract gold and the accompanying mineral complexes from all products of classification including slurry (a class -0,1 mm);there is no enrichment on lock devices (are established only on control operations);the continuous controlled exit of a concentrate is carried out.The offered technology will find broad application at an assessment and operation of technogenic complexes, off-balance and unpromising objects of precious metals.

The paper deals with principal results of exploration carried out in the Sredne-Ishimbinskaya area. The area studied lies in the central part of the Yenisei gold province. Data are presented on the prospecting methods for lode gold deposits in complicated mountain-taiga landscapes.Еxploration carried out in several consecutive stages. At first prospective area studied by a series of basic geological and geophysical profiles with a complex of geological, geophysical and geochemical research methods, and geochemical prospecting carried out by the leakage flux. As result revealed several potentially ore-controlling plicate-discontinuous dislocations zones, the most perspective localized in the southern part of the area. In the next stage of exploration within the southern part of the area carried out geochemical prospecting on the secondary dispersion halos, schlich and lithogeochemical sampling at the depth of 0.8-1.0 m and geological prospecting routes. As result of second stage of exploration revealed several potentially gold-bearing mineralized zones within the zone of ore-controlling fold-discontinuous dislocation plicate-discontinuous dislocations zone. In the third stage of exploration carried out excavation of pits at intervals of 10-20 m between the pits and bulldozing trench depth of 1 m to localize mineralized zones. The lower productive horizon of deluvial deposits in pits sampled by schlich and lithogeochemical methods. Bedrock in pits sampled by trench sampling. Several sectors were allocated for trenching by bulldozer as result of geological documentation and sampling was the final stage of exploration. The most mineralized areas which are potentially ore zones within the gold-bearing mineralized zones, were trenched to the bedrock and then crossed by a series of boreholes. As result, we have identified ore intersection - the epicenters of the highest gold grades within the mineralized gold zones.For the first time in the region we prognosticate the detection of low grade-high tonnage gold mineralization localized in carbonate-terrigenous sequence of the Aladyinskaya and Kartochki series of the Middle-Upper Riphean.

The results of a comparative analysis of the different properties of nanorelief gold sulfides are presented. The morphology and microtopography of auriferous pyrite and arsenopyrite are described. The mechanism of adsorption of gold on the surface of sulphides, which is based on redox reactions isexplained. It is shown that gold is adsorbed largely on arsenopyrite surface than on pyrite surface. The mechanism of adsorption of gold sulfide by surface defects is explained.

The article shows the main results of researches conducted on the territory of the Mednogorsk ore district, located in the Southern Urals. Predecessors applied the existing geological concepts and paradigms to a structure of South Ural. As a result, there is a situation that the objective geologicalpicture still isn’t present. Dependences of minerals of different type on structural elements it isn’t observed though huge actual material is saved up. The view of the territory of the Mednogorsk ore district from the point of view of presence at the historical past of large volcanic structures, which were a source of volcanic sedimentary rocks and industrial concentrations of ore minerals, is given in the article. As a result of the carried-out paleovolcanic reconstruction the Mednogorsk paleovolcanic structure was allocated. Visible diameter of the structure from 30 km in northeast and to 60 km in the northwest direction, other part is overlaid by sedimentary Devonian, Carboniferous and younger deposits. Formation of the structure took place in three stages from the Cambrian to Devon. In the first (basaltic) stage there was an effusive volcanism as a result of which the mafic shield volcano was formed. The shield volcano consists of the volcanic center with a diameter of 11х8 km, the slope (on removal to 20 km from edge of the volcanic center) and the distal area, put by the breeds relating to vent, slope and distal facies respectively. The second (rhyolitic) stage is also effusive volcanism, but it is the stratovolcano, created over the shield volcano, and has mainly felsic, and less intermediate chemical composition. In a structure are allocated it’s own vent, slope and distal facies. In the third stage (a post-effusive era) of structure formation there was an intra facial introduction of intrusive bodies of various forms. The ultramafic bodies are widespread. The era of volcanism was replaced by the era of intensive destruction to what accumulation of terrigenous deposits of Devonian age testifies.

Ecological criteria for ore-bearing geological formations are stable association of the same type of geological and ore formations, regardless of their age. Analyzed geochemical and metallogenic specialization and zoning of structural-material complexes.In ontogenesis specific geological formation in its full cycle outlines different levels of geochemical specialization: Syngenetic, premineral originally inherent throughout the volume of the formation; geochemical specialization sinrudnaya arising during rudokontsentrirovaniya, including simultaneously with the formation of the formation; geochemical specialization of secondary, primary nakradyvayuschayasya on geochemical characteristics of the formation due to the influence of her party not paranenetichnyh hydrothermal solutions.The total system chain operations metallogenic prediction and search for information about the geochemical specialization of geological formations and their components enable the following: produce formational interpretation found in the multi-purpose geological and geochemical mapping of anomalous geochemical fields; producing zoning study area on the types of geological formations having varying potentially mineralized with the release of the most productive subformations, phases and facies; to give quantitative estimates of probable resourcesGeochemical criteria of ore-bearing geological formations are primarily in stable correlations petrochemical features ore-bearing rocks and the corresponding fluctuations in the mineral composition of ores (for example, the correlation of potassium content in silicate ore-bearing volcanic rocks ore- bearing volcanic geological formations and ratios of copper and lead ores of pyrite family ore formations).These criteria should be considered in regional and local assessments of the prospects of ore-bearing geologic formations.

The reorganization of the sector of the land management in general and the urban land tax in particular, stays nowadays, one of the necessities that must drive to the sustainable development. To reach there, every plot of land has to have Land Title (LT). That’s why, the Government of the Republic of Benin has introduced the massive creation of Land Titles in certain urban areas of the country. During the management of this project, several difficulties have been resolved while others continue. Most of these difficulties find their foundation in the essence and the tenures characterizing the beninese land system. That’s why it will be necessary to regulate them by reforms as legislative as institutional and structural.
