This paper studies the properties of metallurgical briquettes iron ore concentrate with coke screenings and liquid glass as a binder. The are produced by one-sided pressing in closed die mounted on plates vertical press force 100 kN. were carried out laboratory Spidermash LLC. following determined: density, impact strength compressive (for green dry briquettes). functional dependences mechanica...

Given that mythmakers must construct stories that ore comprehensible to their audience, it is reasonable to expect stories to be conceptually natural even when their topics deal with the supernatural. Thus, OS stories ore adapted to human conceptual structure, they should reflect characteristics of that structure. An examination of the types of magical transformations in Ovid’s Metamorphoses on...

The need for sustainable catalysts for an efficient hydrogen evolution reaction is of significant interest for modern society. Inspired by comparable structural properties of [FeNi]-hydrogenase, here we present the natural ore pentlandite (Fe4.5Ni4.5S8) as a direct 'rock' electrode material for hydrogen evolution under acidic conditions with an overpotential of 280 mV at 10 mA cm(-2). Furthermo...

Smoliński, Central Mining Institute, Department of Energy Saving and Air Protection, Poland In this study composition of sinter mixtures used in Polish sinter plants were established. Seven sinter mixtures composition were examined, based on iron-bearing materials, admixtures and fuels.

Open Relation Extraction (ORE) overcomes the limitations of traditional IE techniques, which train individual extractors for every single relation type. Systems such as ReVerb, PATTY, OLLIE, and Exemplar have attracted much attention on English ORE. However, few studies have been reported on ORE for languages beyond English. This paper presents a syntax-based Chinese (Zh) ORE system, ZORE, for ...

The recovery of gold by ore leaching is influenced by the size of the particles and the chemical environment. The effect of particle size on the dissolution of gold is usually studied using mono-size particles as the gold in solution comes from the ore of a unique leached particle size. This paper proposes a method to estimate the gold dissolution as a function of particle size using a bulk ore...

−− Copper recoveries using two methodologies of acid leaching of a low-grade ore are reported in this work. The ore, abounding in oxidized species, was from Barda González reservoir in Neuquén province, Argentina. In the first methodology, cells of Acidithiobacillus thiooxidans were inoculated into a column containing the ore and sulfur as energy source. In the second one, a bioreactor with imm...

Ore grade estimation is a key aspect in the evaluation of a mineral deposit. In this paper an alternative approach to currently applied methods of ore grade estimation is presented. This alternative approach involves a modular neural network system integrated in a state of the art 3D resource modelling package. The need for a new method of ore grade estimation comes from the difficulties in app...
