Mineral water and drinking water are two vital and immediate needs for human beings. The origin of 80\% of human diseases are unavailability of healthy water.75 percent of people in developing countries are deprived of facilities for water. Actually , healthy water is scarce and expensive. Pollutions descend the quality of water by changing it physically, chemically and biologically. Some of the pollutions are decadence and can be degraded easily, like human, animal and agricultural drainages. Some of the pollutio...

A significant element characterizing a lasting development in Braila Plain region, but also in any other similar area, would be an environment factor i.e. the water, with an increasing importance when considered against the high dryness background. Generally speaking, both the consumed water and the consumption structure reflect the quality and quantity of water resources and, implicitly, the economic potential of the region at issue. As for Braila Plain, here there is a paradox to be considered : even if the regi...

The climate, morphometric and lythological conditions confer certain peculiarities upon the waters resources of the northern-eastern Romanian Plain. One can say about the Braila Plain hydrographic network that it is poor and this is due to the discharge, situated under the value of 1 l/sqkm, but also to the very low relief energy. The allochthone rivers : the Danube, Siret, Buzau and Calmatui are affected by the refief climate conditions and also by the size and the geographic position of the hydrographic basins.

Significant surface flow redistribution is the result of solid mineral deposit exploitation. North taiga region is characterized of high bogging level. Raised bogs of north taiga region are subjected to surface flow redistribution. Woodless raised bogs of the Russian north were historically used as routes of track-type cross-country vehicles.

Geochemical prospecting is one of the most useful methods in mining deposits exploration. For most of minerals and elements, geochemical data are reliable and helpful. As these methods are not expensive we can use theme in large scale. But non of these methods ( based on sampling from rocks, stream sedimentary, soil, water etc.) are complete and need complementary methods such as heavy mineral study, geophysics, remote sensing etc. Heavy mineral study is one of the best complementary methods. Based on this method ...

Multivariate analysis is one of the base stage in heavy geochemical prospecting (heavy mineral study). Factor and clustering analysis identify different type of mineralization and the relation between minerals in studied area. But in these methods for each mineral it is necessary to be at least 10 valid samples. Therefore some minerals can’t be analyzed by such methods and we miss some minerals in multivariate analysis and can’t identify the relation between these minerals and others. Jaccard coefficient can b...

The aim of this paper is to evaluate the suitability of a coal sample from the mine CSA for bacterial leaching. Laboratory research used a pure bacterial culture of Thiobacillus ferrooxidans . The results showed that bacterial leaching was effective, with a one month leaching time, when 68\% of total sulphur and 68\% of pyritic sulphur was leached. The paper describes changes to the pyrite during and after bacterial leaching.

Titanium; the ninth mose abundant element, occurs in nature mainly as ilmenite (95\%) and rutile (5\%). Ilmenite is an economically important mineral. Ilmenite forms as a primary mineral in mafic igneous rocks and is concentrated into layers by a process called “magmatic segregation”. It crystallises out of magma relatively early before most of the other minerals. As a result, the heavier crystals of ilmenite fall to the bottom of the magma chamber and collect in layers. It is these layers that constitute a ri...

This paper presents the results of magnetic separation tests for the recovery of colemanite from the ore and the tailings produced in Kestelek (Turkey) Processing Plant. Crushed ore (30.76\% B2O3) and tailings (31.76\% B2O3) samples were wet screened and classified into different size fractions. Size fractions coarser than 75 $\mu$m were subjected to three-stage magnetic separation using a high intensity permanent magnetic separator. The mineralogical composition of the ore and the tailings appears to enable gangu...

According to the valid Slovenian legislation the mineral raw materials are numbered among the natural resources that are part of natural goods important for satisfying Man’s material and spiritual needs and interests ( Art. 5 of Environment protection law). In this sense the mineral raw materials represent a specific category of goods that are not free to be appropriated by somebody. They are the ownership of the state, and they can be extracted only under a special permission – the concession. The ownership o...

With organizing the excavation tehnology of loose raw materials through the boreholes, considering the complexity of technological operation, the most important thing is to calculate technical-technological parameters of exploitation and to make an optimal selection of pump aggregate, pipe line and pulp line, and also to project and construct the equipment for drilling and obtaining of concrete deposit conditions since there is no serial production.

Numerical modeling of water flow has developed to a standard in surface water and groundwater operations. Modeling of water flow in underground mines requires a special approach due to interlinked cavities. The same principle problem occurs in strongly jointed, inhomogeneous groundwater systems, like karst or jointed systems with a statistically well defined structural pattern. The key to simulate hydraulic processes in such environments is the reduction of model-balance-cells, following the requirements of the fl...
