The removal of impurities in molybdenum concentrate has become a new challenge for enterprises due to the cancellation pickling. Whether impurity minerals can be converted into soluble ions during roasting is important by current water washing. In this work, interaction between various elements treatment process was studied simulation experiments combined with X-ray fluorescence (XRF) and diffr...

In this study, a clean pellet production method of calcium roasting and sulfuric acid leaching vanadium from titanium magnetite concentrates is proposed, which can effectively separate iron, the pellets after extraction be used as raw material for iron making secondary roasting. During experiment, only 2% Ca(OH)2 was added calcifier to make pellets, extracted by calcination. Under optimum condi...

The recovery of rare earth elements (REEs) from secondary resources, particularly coal-based materials, has recently received attention due to supply and demand imbalance. Research reported date indicates that a high REE can be realized when treating bituminous coal sources using strong acid solutions approximately100 g/L or higher. This study introduces an approach enhance the total (TREE), es...

Continuous counter-current extraction of rhenium from roasting dust leach liquor was carried out using a mixer-settler extractor. Tributylphosphate was used as the extractant diluted in kerosene. The effects of the flow rates and extraction stages number were investigated. The extraction efficiency was affected by the flow rates of the aqueous and organic phases, and its mechanism was qualitati...

An experiment has been performed to utilize the wasted and disposed fish from White Nile River after simple heat treatments (Sun drying, roasting, direct boiling and indirect boiling) in layers’ rations from 19 up to 40 weeks to replace the imported concentrate with the levels of 0, 1.5, 3.5 and 5% for all heat treatments. The crude protein of treated fish was 50.75, 52.50, 50.55 and 50.05% for...

Recently, processed foods have become an important part of human eating habits. However, several processing techniques, such as dehulling and roasting, are applied to raw foods. Roasting is a thermal process that depends on temperature time improves the extraction yield oil by generating pores in oilseed cell walls. Sesame (Sesamum indicum L.) annual plant belonging Pedaliaceae considered be on...

The aim of this study was to determine the best interaction between roasting time and temperature peaberry beans from cherry fruits combined with three different degrees roast in order archive results for sensorial attributes as well verify changes physical parameters. curves showed similarity profiles, indicating proper conduction process. According ways roasting, significant differences at 5%...
