Abstract

The article describes the development stages of an adequate regulatory structure for the slope stability in open pit mines. Some supplementary factors that have influence on stability of slopes in open pit mines in the gravity–tectonic stress field are discussed. The main trends of research of pitwall rock mass in operating surface mines are presented, and the necessity of determining the tectonic stresses in pitwall rock mass and taking into account their impact on slope stability is emphasized. The algorithm is developed for justifying slope parameters for open pit mines under tectonic stresses, the drilling-and-blasting principles are formulated for the operation in pitwall rock mass, and the methods are proposed to mitigate the blasting-induced impact on adjacent rocks.

Abstract

The article describes determination of oxidizability and spontaneous combustion of ore and rocks as a case-study of the Oktyabrsky deposit. The rate of oxidation of sulfide ore increases after watering. The authors present the studies on sensitivity of ore and enclosing rocks to spontaneous combustion, as well as on gas emission in isothermal conditions and in heating. It is found that sulfide ore, hornfels and gabbro-dolerite are sensitive to spontaneous combustion.

Abstract

The author investigated the modes of thermal and heat-and-radiation treatment of ferruginous bauxite from Vezhayu–Vorykva deposit and revealed different mechanisms of mineral transformations. Under thermal treatment, oxo-hydroxides transform into anhydrous iron and aluminum oxides, while under heat-and-radiation treatment, scattered microelements form metal alloys and new minerals. It is recommended to ground ferruginous bauxite processing on basic science, first of all, nanomineralogy, and on phenomenon of phase heterogenization. This approach can promote an increase in recovery of fine particles of aluminum and other valuable components from low-grade bauxite and red mud by eco-friendly techniques.

摘要 作者研究了 Vezhayu-Vorykva 矿床铁铝土矿的热处理和热辐射处理模式，揭示了矿物转化的不同机制。在热处理过程中，氧化氢氧化物转变为无水铁和铝氧化物，而在热辐射处理过程中，分散的微量元素形成金属合金和新矿物。建议将铁铝土矿加工建立在基础科学之上，首先是纳米矿物学和相异质化现象。这种方法可以促进通过生态友好技术从低品位铝土矿和赤泥中回收更多的细颗粒铝和其他有价值成分。

Abstract

The article presents evaluation of preparability of iron ore from Yakovlevo deposit, Kursk Magnetic Anomaly, using magnetic, gravity and X-ray radiometric methods of coarse particle separation. The detailed study involved a material with particle size of (-100+25) mm, containing 25–45% Fe(_mathrm{total}) and 3–35% of Fe(_mathrm{magn}) and requiring dressing. It is found that effective separation of the initial feedstock into ore and dirt is ensured by the X-ray radiometric method of separation of coarse particles (-50+25) mm in size. At the analytical parameter equal to 2, the increase in the content of Fe(_mathrm{total}) in the ore product reaches 1.18 times at the loss of 5.52%.

Abstract

The article discusses tectonic stresses determined in the West Sakhalin terrain using different tectonophysical methods. The reconstruction of the stress field in coal fields in Sakhalin is implemented using the graphical method of orientation finding of stress axes in fractures and faults (at 16 observation points). The supplementary on-site tectonophysical studies made it possible to estimate the preferred orientation of the main slickensides of different kinematics and to reconstruct on this basis the local stress tensors at 53 observation points. The typical stress state of the West Sakhalin terrain is horizontal tension.

Abstract

The article describes the experimental studies on the recovery of chromite ore obtained from the Askale-Kop deposit (Erzurum/Turkey) using a laboratory-type KC-MD3 Knelson concentrator. For this purpose, the parameters of pulp feed rate, fluidization water flow rate, pulp solids ratio bowl speed and particle size were examined as variables in the experimental studies. As a result of the experiments, the maximum Cr2O3 grade was obtained at 54.68% in chromite concentrate at fluidization water flow rate of 12 l/min, pulp feed rate of 1.5 l/min, pulp solids ratio of 20% and bowl speed of 800 rpm. The highest concentrate recovery value (76.85%) was obtained at fluidization water flow rate of 6 l/min, pulp feed rate of 1.5 l/min, pulp solids ratio of 20% and bowl speed of 1080 rpm.

Abstract

The authors provide the theoretical and experimental justification for the effective methods of modification of saponite—pillaring and thermal treatment—which ensure production of sorbents possessing high cation exchange capacity relative to cations of heavy metals. The mechanism of pillaring and thermal modification of a saponite-containing product at the temperature of 625 °C involves expansion of layers of the mineral, formation of additional acid or redox sites (pillaring) and restructuring with generation of metastable phases (thermal treatment). Modification of saponite increases static exchange capacity relative to copper cations by 2 times after pillaring and by 2.6 times after thermal treatment.

摘要 作者从理论和实验上论证了皂石改性的有效方法--起丸和热处理--这些方法可确保生产出相对于重金属阳离子而言具有高阳离子交换能力的吸附剂。在 625 °C 温度下对含皂石产品进行成丸和热处理改性的机理包括矿物层膨胀、形成额外的酸性或氧化还原位点（成丸）以及产生析出相进行重组（热处理）。皂石改性后，相对于铜阳离子的静态交换容量在成岩后增加了 2 倍，在热处理后增加了 2.6 倍。

The mechanism of pillaring and thermal modification of a saponite-containing product at the temperature of 625 °C involves expansion of layers of the mineral, formation of additional acid or redox sites (pillaring) and restructuring with generation of metastable phases (thermal treatment). Modification of saponite increases static exchange capacity relative to copper cations by 2 times after pillaring and by 2.6 times after thermal treatment.</p>","PeriodicalId":16358,"journal":{"name":"Journal of Mining Science","volume":null,"pages":null},"PeriodicalIF":0.8,"publicationDate":"2024-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140117559","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
