Abstract Profitable exploitation of mineralised material from the earth’s crust is a complex and difficult task that depends on a comprehensive planning process. Answering the question of how to plan production depends on the geometry of the deposit, as well as the concentration, distribution, and type of minerals in it. The complex nature of mineral deposits largely determines the method of exploitation and profitability of mining operations. In addition to unit operating costs and metal prices, the optimal recovery of and achievement of maximum profit from deposits of sulphide-oxide ores also depend, to a significant extent, on the level of technological recovery achieved in the ore processing procedure. Therefore, in defining a long-term development strategy for open pits, special attention must be paid to the selection of an optimal procedure for ore processing in order to achieve the main objective: maximising the Net Present Value (NPV). The effect of using two different processes, flotation processing and hydrometallurgical methods (bioleaching acid leaching), on determining the ultimate pit is shown in the case of the Kraku Bugaresku-Cementacija sulphide-oxide ore deposit in eastern Serbia. Analysis shows that the application of hydrometallurgical methods of processing sulphide-oxide ore achieved an increase in NPV of 20.42%.

A large number of different strategies at the central, regional and local level have been done in the last decade in Serbia. Studies on their quality show that quite a number of strategic documents meet the standards in their form, but in terms of the content, they do not have a clear strategy and strategic projects, they overlap and are poorly intercoordinated. The paper identifies and discusses the stages and steps in the strategic planning process, that are crucial for formulating long-term sustainable development solutions for a specific territory and the improvement of its citizens' lives. Its main thesis is that the local strategies lack strategic thinking, i. e. that the solutions are not based on its products. Attitudes about the causes of the lack of the strategic in the strategies are illustrated with a specific example: the planning process and the content of the Development strategy of the City of Pančevo.

Mining operations determine a long-term production schedule, often to maximize net present value. For a time horizon of between years and decades, optimization models seek the extraction times—with monthly or yearly fidelity—of three-dimensional, notional blocks of ore and waste within a deposit to satisfy spatial precedence constraints, as well as resource constraints on the amount of material extracted and sent to the mill. With algorithmic advances, as well as those in mine planning software and in hardware, we are able to solve instances with a decade-long horizon at daily fidelity. The resulting objective, repeatable, and defensible schedules inform production and maintenance supervisory decisions based on resource availability, that is, loaders, shovels, haul trucks, and mineral processors. We implement our solutions at the Turquoise Ridge underground gold mine in Nevada, United States. These solutions indicate more than a 2% increase in total ounces extracted over a decade while decreasing development footage by as much as 11% over the same time horizon. Furthermore, we are able to incorporate rules governing a shared resource and to evaluate binding versus nonbinding capacity constraints.

Strategic Ability

The development strategy is a long-term roadmap of the company's activities, which makes it possible to achieve higher performance in relation to competitors. Almost all managers of agricultural enterprises in the process of strategic management face a number of problems, such as the choice of appropriate tools for strategic analysis and methods for building a strategy. This is based on the fact that different agricultural enterprises have different existing capabilities, available resources and strategic planning needs. Depending on the strategic ability of agricultural enterprises, it is proposed to use various tools of strategic analysis and methods of strategy development. Based on the conducted research, there was formed a mechanism for implementing strategic planning at an agricultural enterprise. It consists of three stages. The developed mechanism was tested at a private agricultural enterprise 'Ridna Zemlia' (Native Land) with the typical main indicators of economic activity in the Ivano-Frankivsk region. At the first stage, using a balanced system of economic indicators, it was found that this enterprise has an average level of strategic ability. Following the recommended strategic analysis tools, at the second stage of strategic planning, SWOT analysis of an agricultural enterprise was conducted identifying its strengths and weaknesses, existing opportunities and threats. At the third stage, a roadmap for implementing the strategy was developed within the framework of using the road mapping method, which is allowed by the appropriate level of strategic capability. The main strategic goal of the developed strategy is to ensure sustainable profits in the long term by increasing the productivity and efficiency of agricultural production. Based on this, the following strategic tasks were proposed to implement: the introduction of a new technology, which consists of constant monitoring of the herd of cows, opening of a new farm to expand the existing market and increase production volumes, the construction of a pellet boiler farm using biofuels, as well as the formation of a personnel training plan and the development and implementation of training programs for employee development.

The article presents the key results of scenario projections that underpinned the Strategy for long-term low carbon economic development of the Russian Federation to 2050, including analysis of potential Russia’s GHG emission mitigation commitments to 2050 and assessment of relevant costs, benefits, and implications for Russia’s GDP. Low carbon transformation of the Russian economy is presented as a potential driver for economic growth that offers trillions-of-dollars-worth market niches for low carbon products by mid-21st century. Transition to low carbon economic growth is irreversible. Lagging behind in this technological race entails a security risk and technological backwardness hazards.

First Time

The study was targeted at developing a methodology for constructing a macroeconomic performance index at a provincial level for the first time in Vietnam based on 4 groups of measurements: (i) Economic indicators; (ii) oriented economic indicators; (iii) socio-economic indicators; and (iv) economic - social – institutional indicators. Applying the methodology to the 2011 - 2015 empirical data of all provinces in Vietnam, the research shows that the socio-economic development strategy implemented by those provinces did not provide balanced outcomes between growth and social objectives, sustainability and inclusiveness. Many provinces focused on economic growth at the cost of structural change, equality and institutional transformation. In contrast, many provinces were successful in improving equality but not growth. Those facts threaten the long-term development objectives of the provinces.

Sustainability of mining companies is of of high concern. The problem is specifically acute at companies that are monotownor monosettlement-forming. Sustainability of a mine depends in many ways on product quality and production resource-intensity. This article discusses formation of mineral quality indexes in terms of an open pit chrysotile mine. The studies took into account specific features of operation procedures implemented by each structural division of the mine. The analysis has found managerial and technological inconsistencies which affect quality and marketable product output, as well as efficiency of the mine in whole. The background for efficiency enhancement at a company is, by the authors’ opinion, consolidation of personnel subject to the single development strategy, namely: improvement of production and control efficiency, as well as use of available reserves and resources by means of better setup for production. The proposed approaches to planning mining operations and forming mineral quality allow higher quality of processing stock. In addition, a new model proposed for interaction between structural divisions of a mining company ensures improvement of general production indexes.
