Mining of minerals is associated with waste that needs to be dealt with, e.g., safely deposited or, if possible, reused. From 2010 to 2016, 6,182,277 Mg of waste was deposited during mining of rock raw materials in the Lower Silesia region in Southwest Poland. Extraction activities were responsible for 46.95% of that waste, while mineral processing was responsible for 53.05% of that waste. This study analyzed the spatial and temporal distribution of waste resulting from mining rock raw minerals in Poland’s Lower Silesia region. In the study, an inventory of waste deposited during rock raw mineral mining and processing was prepared. Then, a geographic information systems (GIS) database that included information on the quantity and quality of waste generated during rock raw mineral mining and processing during the 2010–2016 study period was created. It was used for assessment of the variation of waste distribution and density in time and space with GIS kernel density estimation (KDE) functions. Spatial context of mining waste production and distribution over a period of 7 years in Lower Silesia were analyzed and presented graphically. The study revealed increasing accumulation of mining waste and helped to identify spatial clusters of its deposition in the region. Based on a literature study and the identified main waste types, the potential of selected types of this waste for re-use was analyzed and prospective uses were proposed. The methodology of quantitative and spatial analysis used in this research can be applied to studies in other regions coping with the problem of a large amount of mining waste.

Animal feed knife is a tool that serves to cut and chop animal feed consisting of grass as the main ingredient with additives such as bran, herbs, centrate, cassava, tofu pulp and others. Therefore, as a cutting tool must have the properties of friction resistance, impact resistance, and have good sharpness, so that the material chosen is Ni-Hard 1. The use of centrifugal casting method was chosen because it has the advantage of being able to make castings with relatively thin thickness this is due to the influence of the centrifugal force on the distribution of metal liquids throughout the cavity in the mold. Case study in this study is the use of centrifugal casting methods as an alternative to gravity casting methods to overcome defects of misruns. This research was conducted to investigate the effect of speed on the formation of castings products. The method that was carried out began with a literature study on centrifugal casting, and continued by determining the material, the temperature of the cast is in the range 1250ºC - 1300ºC, and the type of mold. The next step is to do work drawings, pattern making, mold making, casting processes, fettling processes, and analysis. With variations in speed of 200 rpm, 300 rpm and 400 rpm, it can be seen the optimal speed for making this product. The results of this study obtained optimal speed at a speed of 300 rpm to make good quality of animal feed knife products.

The article considers the characteristic features of the development of interaction between international and Russian transnational capital subjects, which appear in raising national corporations to a transnational level, in the penetration of leading world’s firms in the national spheres of investment, production and distribution of goods on labor markets. Consequently, the development of relations between national companies and transnational corporations (TNCs) in the domestic economy has features that distinguish them from devel-oped countries. Currently, the tendency of Russian TNCs integration into the production chains of international corporations in developed countries as a supplier of raw materials has been formed and consolidated. Thus, the relations of Russian multinationals with world corporations and the state are formed according to their own structure. However, the quality of relations between Russian subjects of transnational and national business lags significantly behind those relationships that are realized in the international system of transnational capital.

Reliable feasibility analysis of potential exploitation of a mining waste deposit poses a great challenge. One of the most crucial parts of this process is the approximation of the deposit volume. In this case study we propose a novel method of tailing pile volume estimation using open remote sensing and cartographic data. For selected piles, the difference between the proposed and classical approach reach 50% of the pile volume, which is a significant change in the potential value of the deposit.

Drinking water quality has become a serious issue in many countries due to the scarcity of fresh water resources. Water quality monitoring is the first step for the management and conservation of aquatic system. The contamination of OrganoChlorine Pesticides (OCPs) is very harmful for the environment and human beings. The presence of OCPs in surface water and in the bottom sediment in the Chalakudy River was investigated to evaluate the pollution load and distribution level of OCP seasonally over a period of 3 years from January 2013 to December 2015. Surface water sample and bottom sediment were collected from nine different sites (upstream, midstream and downstream) and analyzed for their profile of important physicochemical parameters and for persistence of OCP. To know the present trends in the river clearly ,temporal  distribution  and spatial distribution of OCPs and other parameters are studied based on three season(winter, summer, and monsoon).Obtained trend in each  year  were compared  through sampling and analysis.

Thermo Plastic Acrylic resin has an important role in the manufacture of spray paint, namely as a binder or binder. The resin in paint has a function as a film formation, has adhesion to the substrate as well as pigment binders and additives, so that to produce a spray paint with good quality mechanical properties, PT X must be selective in controlling the quality of the raw material for Thermo Plasic Acrylic Resin. The purpose of this study was to determine the problems faced by PT X related to the quality of Thermo Plastic Acrylic Resin raw materials, to identify the most dominant factors affecting the quality of these raw materials and to formulate the most appropriate solutions to be applied in improving the quality of these raw materials. This research uses observation, interview, and literature study methods. Sources of data came from stakeholders and quality control staff of PT X. This study used check sheets, histogram diagrams, u-control maps, and fishbone diagrams to complete the analysis process. From the test results of the Thermoplastic Acrylic Resin raw material, it is known that the factor that causes rejection is due to adhesion, namely 53.57%, gloss 33.33%, and dry touch 13.10%, all three of the total raw materials that are rejected when the raw material is applied in form paint and spray on the film plate. The most dominant cause of reject was poor adhesion, namely 53.57% of the total reject raw materials.
