different samples have been prepared from different products in chadormalu iron ore concentrator plant: low intensity magnetite separators concentrate (magnetite concentrate), reverse flotation tail (final hematite concentrate), flotation concentrate (apatite concentrate), final tail (l.i.m.s. tail + reverse flotation concentrate+ apatite flotation tail). the samples were used for rare earth el...
This study aimed to explore concentration of a low grade sulfide-oxide lead-zinc sample containing 2.3% Pb, 1.91% Zn taken from Changarzeh mine, South Natanz, Iran. The effects of different parameters such as type and dosage of collector, milling retention time, dosage of sodium sulfur and its preparation time, application of sodium silicate, pH and solid content were investigated in relation t...

this paper tries to determine an optimum condition for the flotation operation of the alborz-sharghi coal washing plant. for this purpose, a series of comprehensive experiments have been conducted on representative samples from feed of the flotation system of the plant. four operational variables such as the collector dosage (fuel oil), the frother dosages (mibc), the pulp density percent and t...
fifty-nine samples of washed and unwashed leaves of 4 species of plants in tehran and 24 similar samples of the suburb (as control) were analyzed for pb content. a significant difference was seen between pb contents of washed and unwashed urban samples, while no significant difference was observed between the control samples. the mean pb contents of the urban suburb samples were also significan...
