The chrysocolla mineral takes a unique place among the minerals found in the complex oxidized copper ores. For developing the newest efficient methods of processing such ores it is necessary study comprehensively the properties of the chrysocolla mineral. The difficulty is in distinguishing between monomineral fractions from the ore. In literature there are no data of obtaining chrysocolla artificially, there are only different authors' suppositions regarding the mineral formation in the earth crust by means of copper adsorption from solutions by silica. In this connection we for the first time by the method of voltammetry have established the mechanism of forming the chrysocolla mineral during anodic polarization of the electrode in the sodium metasilicate solution. There has been shown a possibility to obtain chiysocolla by means of electrolysis from the water solution of sodium metasilicate. There has been studied the effect of the current density, the concentration of sodium metasilicate, the solution temperature and the duration of electrolysis on the chrysocolla current yield. In optimal conditions the current yield is 78.5 %. There has been carried out a comparative analysis of the obtained by electrolysis chrysocolla with its natural analogue. There have been used methods of IR spectroscopy, differential-thermal and chemical analyses that confirm the identification of the electrolysis chrysocolla with chrysocolla taken as the reference.

The main advantage of the known electrochemical methods is the possibility of obtaining powders with a smaller particle size, which eliminates the additional stage of its processing, i.e. regrinding. The works aimed at obtaining nanodimensional powders of copper oxide compounds that are widely used in the production of antibacterial materials, solar batteries, gas sensors, photovoltaic cells, in semiconductor technology, as well as a catalyst for the oxygen electrode of a fuel cell with a solid electrolyte, are now of ever-greater interest. In this paper by the method of voltammetry there has bee for the first time studied the mechanism of forming copper silicate powder nanoparticles during anodic polarization of a copper electrode in a slightly alkaline solution of potassium silicate. Based on the results obtained, using the method of mathematical planning of the experiment, there has been studied the effect of the current density, the concentration of potassium silicate, the temperature of the electrolyte, the duration of electrolysis on the current yield of the nanosized copper silicate powder. The optimal parameters of electrolysis in galvanostatic conditions have been determined. The chemical analytical method has established the compliance of the electrolysis-produced copper silicate with the formula CuSiO3 center dot 3,8H(2)O. There have been performed the electronic microscopic studies of the synthesized copper silicate powder and the particle sizes have been determined in the region of 50 nm.

In recent decades, the economic processes at both micro and macro levels have been affected significantly by the globalization, resulting in strengthening the ties and interaction between economies, promoting industrial development, tougher sector-wide competition and scientific and technological advancement. It has become increasingly challenging for many businesses to sustain a stable market position, not to mention business growth. It is beyond doubt that by focusing on growth and sustainability, economic entities develop the economy in general. However, it can affect other areas too. For example, expansion of production has a negative ecological impact, causing resource depletion and environmental pollution; and the desire to reduce costs often affects the working conditions and the wellbeing of employees. Recently, economic entities all over the world have been paying special attention to the environmental impact and social responsibility of business, which are two of the three main components of sustainable development. Therefore, the concept of sustainable development has been playing an increasingly significant role in every country in the world. Undoubtedly, many economic entities of today strive to adhere to the principles of sustainable development of business, which include economic success, environmental protection, and social wellbeing. The definition of “sustainable development” was first introduced in 1987 by the International Commission on Environment and Development. Despite this, the process of introducing the postulates of the International Commission into the activities of modern economic entities is still ongoing. Undoubtedly, many modern economic entities strive to adhere to the strategy of sustainable development, shaping their activities in the framework of compliance with the principles of financial success, causing the least damage to the environment and taking into account the social component. It is worth noting that the implementation of the concept of sustainable development in the management of a business entity requires the use of effective tools.
