The article assessed interaction of state and chemical industry corporations by criteria of budget making, tax burden and managerial impact. The appraisal was made on the basis of methodological tools worked out by the author. Within the period from 2012 to 2020 earnings of corporations of chemical industry producing mineral fertilizers grew and exceeded tax revenues of regions of their location, which caused an increase in companies’ taxation potential. However, analysis of tax payments to the budget system by profit tax, property tax, income tax and VAT did not confirm the growth in this pot

Abstract Limestone is part of sedimentary rock, namely non-clastic sedimentary rock formed from chemical or biological processes. The main content of limestone is mineral calcium carbonate (CaCO3), which occurs due to chemical or organic processes. In general, the mineral contents in limestone are 95% calcite calcium carbonate, 3% dolomite, and the rest is clay minerals. Measurements with drones are expected to be an alternative method other than using Total Station (TS). This research aims to calculate the mined area acquisition at the mining area of PT.

In Process Industry, process development traditionally takes a large part of the company's total development efforts, but has nevertheless not received much attention in academic studies. As a part of a larger research project concerning process development in Process Industry, the allocation of company resources to R&D, and to process development in particular, has been investigated in an exploratory survey to R&D managers in European Process Industry (Mining & Mineral Industry, Food & Beverage Industry, Pulp & Paper Industry, Chemical Industry, Basic Metal Industry, and O

Inclusion as a research method was mainly applied in the study of mineral deposit geology in the beginning. In recent years, organic inclusion research has become one of the important means in hydrocarbon exploration. The study of the inclusion can determine the role of diagenesis and reservoir of time and temperature, infer hydrocarbon migration, tectonic movement and paleo-heat flow history, in order to better guide hydrocarbon exploration. This paper mainly discussed research method of hydrocarbon inclusions type and oil and gas inclusion, and summarizes the inclusion of the fracture struct

The aim of the work is to increase the efficiency of enrichment of titanium-iron ores by preliminary high-temperature treatment using new-type separators. This is achieved by substantiating the targeted selective destruction of mineral complexes and changing the magnetic properties of ore minerals as a result of temperature-controlled oxidation reactions.
