This work compared the effect of nitric acid and chloride acid systems on dissolving precious metals of Electrical and Electronic Equipments (EEE). As a result of the revolution of informatics technology, the production of EEE is rapidly increasing in the world. Due to economic growth, technological innovation and market expansion of EEE there is a significant increase in waste of EEEs (WEEE) that presents a new environmental challenge.The results show that the best recovery of gold can be obtained via aqua regia (3HCl=HNO3), with concentration of 1/10 gr/L. The reaction temperature has little effect on the extent of extraction.

Precious Metals Recovery

Waste deposited in ponds can also contain precious metals, as trace elements. Preliminary studies have shown, by chemical analysis, the presence of gold and silver in waste steel. This paper presents some preliminary aspects of experimental work related to gold recovery opportunities from sideritic waste, Teliuc type - stored as a pond and future directions in research. There were two distinct phases considered: gravimetric concentration and removal of three layers from the experimental material, respectively, the treatment of the concentrate with “aqua regia”.

Effective Integration

At present Russia faces the task of great importance - effective integration into the world economy. The success of this process largely depends on the strength of the domestic economy and stable economic growth. To attain such a goal certain changes in economic approaches are required which imply more active, focused and concerted steps in the monetary, fiscal and foreign exchange policy.

Сreation of the stabilization fund has become the main feature of the Russian federal budget for 2004. This instrument provides the opportunity to reduce the dependence of budget incomes on the fluctuations of oil prices. The accepted model does not consider the world experience in building of such funds as the "funds for future generations", and the increase of other revenues from the growing oil prices as well. That can lead to shortening and immobilization of the financial basis of economic growth.

The phenomenon of economic growth is studied by economists and statisticians in various aspects for a long time. Economic theory is devoted to assessing factors of growth in the tradition of R. Solow, R. Barrow, W. Easterly and others. During the last quarter of the century, however, the institutionalists, namely D. North, D. Wallis, B. Weingast as well as D. Acemoglu and J. Robinson, have shown the complexity of the problem of development on the part of socioeconomic and political institutions. As a result, solving the problem of how economic growth affects inequality between countries has proved extremely difficult. The modern world is very diverse in terms of development level, and the article offers a new approach to the formation of the idea of stylized facts using cluster analysis. The existing statistics allows to estimate on a unified basis the level of GDP production by 174 countries of the world for 1992—2016. The article presents a structured picture of the world: the distribution of countries in seven clusters, different in levels of development. During the period under review, there was a strong per capita GDP growth in PPP in the middle of the distribution, poverty in various countries declined markedly. At the same time, in 1992—2016, the difference increased not only between rich and poor groups of countries, but also between clusters.

Conditions and features of the Russian economy development in 2011 are considered in the article. Having caused unprecedented outflow of the capital abroad, rising tension and turbulence on the world financial and stock markets have not broken off recovery of the Russian economy. Crisis recession was overcome. Record-breaking low inflation, rapid credit restoration and active government adjustment neutralized negative effects of the external tension and supported economic growth, having encouraged consumer and investment demand.

In particular, the analysis of the relationship between economic growth and some indicators of nation states - population, territory, direct access to the World Ocean, and extraction of crude petroleum - is presented. Basic problems in the sphere of economic policy in Kazakhstan are formulated.

Main Factors

Russian economy has reached the low level of inflation, but economic growth has not accelerated. Moreover, according to official forecasts, in the following years it will still be low. The article concludes that domestic demand, which is one of the main factors of growth, is significantly constrained by monetary, budgetary and fiscal spheres. The situation in the Russian economy is still hampered by the decline of the world economic growth. The prospects of financial markets are highly uncertain. This increases the possibility of crisis in the world. Leading countries widely use non-traditional measures to support their economies in the similar environment. In the world economy as well as in Russia a principally new combination of factors has emerged, which create specific features of economic growth. It requires special set of measures to stimulate such growth. The article proves that Russian regulators have large unused potential to stimulate growth. It includes monetization, long-money creation, budget and tax stimuli. It is important that the instruments, which will be used, should be based on domestic mechanisms. This will strengthen financial basis of the economy and may encourage economic growth. Some specific suggestions as to their use are made.

The world stands on the precarious edge of an innovative transformation that will on a very basic level modify the manner in which we live, work, and identify with each other. In its scale, degree, and unpredictability, the change will be not normal for anything mankind has encountered previously. We don't yet know exactly how it will unfurl, however one thing is clear: the reaction to it should be incorporated and exhaustive, including all partners of the worldwide nation, from the general population and private segments to the scholarly community and common society. It is The Fourth Industrial Revolution, the digital revolution. The digital revolution has opened way for many impacts. All of the emirates are experiencing the effects of the “Fourth Industrial Revolution.” This revolution reflects the velocity, scope, and systems impact of a digital transformation that is changing economies, jobs, and work as it is currently known.

Sustainable Development Goal 8 to “Promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all” necessitates country level measures across the world. We take forward a comparative analysis of India’s SDG 8 indicator list with both the UN and ILO measurements. We note inadequate measurements on social-protection and rights for non-standard forms of employment including gig work, that are intermediated by ICT platforms. From our analysis we identify some levers to broaden the current indicator measurements to include these non-standard workers as well, to improve social sustainability.
