Clustering Approach

Mineral raw materials prices have been shown to be affected by macroeconomic factors such as aggregate demand and commodity-specific factors (e.g., supply shocks). In addition, it has been shown that certain mineral raw material prices co-move, meaning that they behave similarly during expansion and contraction phases of the international business cycles. In order to assess the behavior similarity of the prices of different mineral raw materials, we propose a method that utilizes extracted features of time series price data and unsupervised learning techniques to create clusters of price movements having similar long-term behavior.

The article deals with the problems of mineral raw material losses of quality and quantity management in developing of large-scale complex-structure and composition deposits of solid minerals. It is shown that a very high degree of mining and geological conditions variability in time and space for the development of mining units is typical for such deposits. This significantly complicates the qualitative and quantitative operating losses setting and accounting of mineral raw materials during its extraction in the framework of existing general and industry regulatory documents. Conceptual principles for face-by-face operational setting of losses and impoverishment of minerals for the conditions of bulk mining of complex-structure deposits with the formation of gross mining flow with economically feasible and specified level of quality (the content of commercial and harmful components) are stated. These principles generally do not contradict effective instructions main provisions and are made to minimize the total operating losses during the processing of several mine sections (faces).

Required Quality

The northern region of the state of Rio de Janeiro, Brazil, has a significant participation in the country ceramic production for civil construction owing to the abundance of raw materials, mainly kaolinitic clays. Each municipality in that region has ceramic industries using raw materials mined from its own deposits. Products such as bricks and tiles may lack the required quality due to the limited know-how on the applied raw material. The present work conducted a technological evaluation of the clayey raw material used in the municipality of São José de Ubá including its potential for ceramic processing at firing temperatures of 700, 850 and 950oC. The results indicated that only the ceramic fired at 950oC conforms to the specifications for water absorption and mechanical strength.

Streszczenie Badaniom zostały poddane trzy próbki z nieeksploatowanego dotąd złoża Dylągówka-Zapady. Charakterystyka surowcowa tych próbek, pochodzących z różnych głębokości złoża, polegała na określeniu ich składu fazowego (przy użyciu takich metod jak: analiza rentgenograficzna, spek- troskopia w podczerwieni oraz analiza termiczna), składu chemicznego, ziarnowego oraz określenia właściwości sorpcyjnych. Badania te wykazały, że kopalina w przekroju pionowym złoża wykazuje zmienny skład chemiczny i mineralny, aczkolwiek generalnie jest zasobna w minerały grupy smektytu (montmorillonit). Zawartość tego minerału ilastego mieści się w przedziale 28^3%. Kolejną fazą mineralną, która ma istotny wpływ na właściwości technologiczne omawianej kopaliny jest opal. Obecność tej fazy krzemionkowej została potwierdzona analizą rcntgenograficzną i termiczną. Stwierdzono, że w próbkach pobranych z różnych głębokości złoża występuje zarówno opal-A jak i opal-CT. Ponadto, w próbce pobranej z nadkładu złoża, stwierdzono także obecność innego minerału palinic podwyższonej ilości smektytów, opalu i zcolitów, wiąże się jej wybitna drobnoziarnistość i dobre właściwości sorpcyjne, co predysponuje ją do wykorzystania jako sorbentu różnego rodzaju zanieczyszczeń.
