Modern approaches to the formation of new generation concretes make it possible to replace part of the fine aggregate with finely ground mineral powders, which are by-products of metallurgical and chemical industries, the construction industry, as well as various substandard quartz sands. In the studies carried out, metallurgical slags (MS), broken glass (BG), dust from gas cleaning of metallurgical production (DGCMP), and ground quartz sand (GQS) were used. The aim of the study is to obtain an optimal flow rate of a hydraulic binder by forming an optimal cement matrix. The dosage of finely ground powders varied in the range of 20-49 % of the portland cement consumption. It has been established that the most acceptable finely ground mineral powders in compositions for the production of vibropress products are: quartz ground sand, metallurgical granulated slag of blast furnace production, gas cleaning dust and ground glass. Powders obtained on the basis of glass scrap can be considered as an additional raw material base in the production of materials for road-building purposes. Operational properties such as water absorption and the rate of concrete curing indicate their prospects. However, the economic costs of collecting, sorting glass, obtaining a powder with a specific surface area of 3000 cm2/g are not reasonable at this point in time.

Ketapang area is one of lower part or southern sub-province of West Kalimanatan Province, which is located geographically between 108o40’ and 111o20’ in Longitude and between 0o20’ and 3o04’ in Latitude. This area has various of industrial mineral resources, for example quartz sand. Quartz sand or also calledwith white sand is the reasult of rock weathering that contents main mineral, such as quartz, and felsdpar. Then, the result of weathering is cleaned and transported by water or wind and deposited in the stream side, lake or sea. In this paper will bedescribed concerning to locations, characteristics, and usages of quratz sand in Ketapang area, West Kalimantan Province. Based on chemical or laboratory analysis and interpretation, the quartz sands can be used as glass industry, cement industry material, and moulding industry.

Abstract Metallurgical slag is one of the most common industrial wastes. Many of these wastes are not stable over time, by reacting with water and air, continuously generating emissions of heavy metals. Metallurgical slag processing is necessary for at least two reasons: reducing pollutant emissions and broadening the raw material base. The recovery of these slags is very difficult because they are the result of metallurgical processes that aimed to fix metals considered impurities in chemical matrices as stable as possible. This paper presents the initial research on the behavior of metallurgical slags against different leaching technologies.

To use effectively internal raw material base, JSC “Ural Steel” accomplished I category major overhaul of the blast furnace No. 2. The main purpose of the overhaul was to design a rational profile which could ensure an ability to operate with a charge containing 95 % of Mikhailovskii GOK (mining and concentrating plant) pellets having basicity of 0.5 by CaO/SiO2. The blast furnace No. 2 having useful volume of 1232 m3, was constructed by design of Danieli Corus, the Netherlands, and was blown in on December 30, 2020. In the process of guarantee tests, step-by-step increase of Mikhailovskii GOK pellets (Fetotal = 60.5 %, CaO/SiO2 = 0.5) content in the charge iron ore part was being accomplished from 55 to 95.1%. Charging of the blend containing pellets in the amount of 55% of iron ore part, was done by charging system 4OOCC + 1COOCC (Ore - Coke) with filling level 1.5 m. Under conditions of pellets part increase in the blend, the charging system was changed to decrease their content at the periphery, to increase it in the ore ridge zone and make it intermediate between periphery and the ore ridge. At the pellets share in the iron ore raw materials 0.75 the charging system was used as the following: 3OOCC + 1COOC + 1COOCC, while at the content 95.1% the following charging system was used: 2COOC + 2COOC + 1COOCC. It was noted that in the period of guarantee tests the furnace running was smooth. The average silicon content in the hot metal was 0.70% at the standard deviation 0.666. Sulfur content in the hot metal did not exceed 0.024%, the blowing and natural gas consumption figures were 2100 m3/min and 11000 m3/min correspondently, oxygen content in the blowing 26.5%, hot blowing and top smoke pressure figures were 226.5 and 109.8 KPa correspondently. The productivity of the furnace was reached as high as 2358 t/day at the specific coke rate 433 kg/t of hot metal. After guarantee tests completion, the pellets content in the iron ore part was decreased gradually from 95 down to 50%. The decreasing was made by 5% in every 6 hours of operation. Application of the mastered technology of the blast furnace No. 2 with the increased share of pellets will enable to stably supply the blast furnaces No. 1, 3 and 4 by iron ore raw materials in the proportion of 30-35% of pellets and 65-70% of sinter.

The paper considers the current state of the mineral raw material base and the construction material market of the Rostov Region. The effect of various factors on the strain-stress behavior of local limestones has been investigated. The scientific and technical literary sources devoted to the processes of rock failure under various loads have been analyzed. The experimental studies have shown that the tested samples of limestone with a high content of cuboidal grains have characteristics comparable to those of the crushed granite stone. It has been concluded that the use of the Rostov Region limestones in the construction industry is competitive and feasible, provided the proper implementation of the engineering measures proposed in their production.
