An improved methodology is presented for assessing the economic feasibility and effectiveness of recycling industrial waste. The based on break-even control mechanism, but at same time provides introduction new evaluation criteria such as threshold conditionality degree ore substitution. Based an analysis, it becomes possible to more precisely predict efficiency. A refined determination lower l...
Novel flocculants have been synthesized on the basis of glycogen. The efficiency of cationic glycogen can be explained in terms of Singh’s qualitative easy approachability model (EAM). The jar test was used previously to evaluate flocculation efficacy, but we have recently shown that a plot of interface height vs. settling times provides a better measure. In accord with the EAM, a one-to-one co...
Desulfomicrobium baculatum is the type species of the genus Desulfomicrobium, which is the type genus of the family Desulfomicrobiaceae. It is of phylogenetic interest because of the isolated location of the family Desulfomicrobiaceae within the order Desulfovibrionales. D. baculatum strain X(T) is a Gram-negative, motile, sulfate-reducing bacterium isolated from water-saturated manganese carbo...
The synergetic utilization of ferruginous gibbsite ores (Al-Fe ores) and manganese (Mn-Fe by the carbothermic co-reduction roasting–magnetic separation process was proposed as an innovative green for recovery valuable metal elements Mn, Fe Al from these ores. In this paper, a ferromanganese crude alloy with 72.47% 10.19% Mn high 85.89% prepared, which produces acceptable feed to produce steels ...
Increased risk of ill-health and diseases has been associated with employment in the ferro-alloy factory. Since measurement of transition metals in human blood and hair along with respective exposure rates, provides a means of assessing individual risk, it has been the most important part of the study. In the study majority of the elements in the transition series, such as, vanadium (V), chromi...
We evaluated the significance of iron and manganese content in sphalerite as a tool for distinguishing between low-sulfidation intermediate-sulfidation epithermal deposits on basis new previously published electron probe microanalyses data Roșia Montană ore deposit available microchemical from Neogene located Apuseni Mountains Baia Mare region, Romania. Two compositional trends Fe vs. Mn were d...
Abstract Although the Mesozoic rocks of Transdanubian Range have been subject a multitude different studies, mineralogical research is largely underrepresented. The clay mineralogy Lower Jurassic (especially Pliensbachian and Toarcian) strata was broadly investigated earlier; however, systematic high-resolution studies remain scarce. Here we present study focusing on Upper Lókút-Hosszúárok sect...
