1. Development of innovation routes for iron ore using high intensity magnetic separators
Abstract The mineral processing of low-grade iron ores commonly generates large volumes of slime, which are disposed as tailings. Modern mining requires strives to eliminate the use of tailings dams in a maximum effort to increase metallurgical recovery, the security and reduction of the operational cost. This research aims for the recovery of iron contained

2. Performance analysis of the beneficiation process of bauxite from the Juruti Mine. Industrial sampling and performance evaluation
Abstract Sampling campaigns were conducted at the industrial bauxite wash circuit of the Juruti Bauxite Mine in Pará, Brazil. The beneficiation circuit consisted of crushing, scrubber washing, wet screening, hydrocyclone classification, and fltration. Considering laboratory processing of samples and statistical analyses of historical operation databases, ma

3. Influence of the addition of KCl and CaCl2 blends on the physicochemical parameters of salted meat products throughout the processing steps
Abstract The objective of this study was to evaluate the effects of different chloride salts (NaCl, KCl, and CaCl2) on the characteristics of salted meat products through the determination of moisture, pH, aw, chloride, ash levels, cooking loss, and instrumental color during the processing steps. Four salted meat treatments were elaborate using the following

6. Consortium of Microalgae for Tannery Effluent Treatment
Abstract Wastewater generated in tanneries have essential elements for microalgae growth, but it has also some toxic compounds that may hinder or restrain the growth of microalgae in this environment. This work tested microalgae consortium growth originating from a deactivated effluent treatment decanter of a complete tannery (beamhouse to finished leather)

7. Hypothyroid offspring replacement with euthyroid wet nurses during lactation improves thyroid programming without modifying metabolic programming
ABSTRACT Objective Determine the milk quality effect during lactation on the metabolic and thyroid programming of hypothyroid offspring. Materials and methods Ten-week-old female Wistar rats were divided into two groups: euthyroid and thyroidectomy-caused hypothyroidism. The rats were matted and, one day after birth, the pups were divided into three grou

8. Protein concentrates from defatted rice bran: preparation and characterization
Abstract The goal of this work is to determine the optimal conditions for the obtaining of protein concentrates from rice bran. The effects of defatting processes applied to this product in laboratory and in industrial scales were investigated. Through two experimental designs were performed, and production conditions to obtain the protein concentrates were

9. Physicochemical and functional characteristics of residual pulp of potato
Abstract Starch-rich liquid effluent is generated after peeling, cutting and washing of tubers during the fries processing. After sedimentation of this effluent is recovered a wet residual pulp, and after drying is obtained dry residual pulp or simply named in this study residual pulp of potato (RPP). In order to convert the effluent into a material easy to

10. Influence of Milling Time During the Mechanical Alloying Process on the Properties of Fe-3Si-0.75P Alloy
AbstractIn this study the soft magnetic alloy Fe-3Si-0.75P (wt%) was obtained by mechanical alloying through powder metallurgy. The processing included the formulation of metallic powder, wet milling for 1 h, 3 h, 6h and 9 h, in an attritor mill using alcohol P.A. as a lubricant. Cold compaction was then performed in a floating die under 600 MPa pressure and

11. Parâmetros de monitoramento na produção industrial de componentes em zircônia parcialmente estabilizada com óxido de magnésio / Monitoring parameters for the industrial production of pieces made of magnesia-partially-stabilized zirconia
Zirconia has been widely applied on production of structural components, mainly due to its great mechanical properties. However, these properties are associated to the zirconia tetragonal and cubic phases, which are stable only on high temperatures on pure material, being necessary doping the material with some oxides to keep these phases at ambient temperat

12. Classification of polymers insulators hydrophobicity basead on digital image processing
Although the hydrophobicity is usually an arduous parameter to be determined in the field, it has been pointed out as a good option to monitor aging of polymeric outdoor insulators. Concerning this purpose, digital image processing of photos taken from wet insulators has been the main technique nowadays. However, important challenges on this technique still
