The recovery process of selenium from Iranian Sar-Cheshmeh copper anode slimes employing hydrometallurgical methods has been investigated. The copper anode slimes are made up of those components of the anodes, which are not soluble in the electrolyte. They contain varying quantities of precious metals like gold, silver, selenium and tellurium. They are being extracted as a by product in th...
recovery of gold and other valuable metals from electronic scrap involves a complex metallurgical flow sheet and requires state-of-the-art recovery technologies that are available in large-scale, integrated smelter and refinery operations. at the end of their use, electronic and other electrical product scrap offer an important recycling potential for the secondary supply of gold and silver int...

In this study, the effect of various doses of ouabain (1, 2, and 5 mg/kg, i.p.) on weight and flow rate of submandibular gland (SMG) and changes in zinc and copper levels in pure saliva and serum of rats was investigated. The time interval between injection of drug and sampling was 30 min. In addition, the effect of a single and toxic dose of ouabain (5 mg/kg, i.p.) in various time intervals (3...
هدف از انجام این پروژه بررسی امکان حل سازی سنگ معدن کم عیار سولفیدی سونگون با استفاده از باکتری است. بدین منظور، ابتدا آنالیز خاک کم عیار سولفیدی معدن به روش شیمیایی و مینرالوژیکی صورت گرفته شد، همچنین آنالیزهای سرندی نیز مورد بررسی قرار گرفته است. سپس امکان سنجی لیچینگ شیمیایی کانسنگ کم عیار توسط آزمایشات بطریهای غلطان مورد بررسی قرار گرفته است. در ادامه به تعیین قابلیتهای میکروارگانیسمهای جدا...
lead, copper, cobalt, nickel, iron and zinc ions form monocitrate complexes (negative charge) in citrate solution which is absorbed on the citrate form of anion-exchange resins (citrate as counter ion) y exchange of citrate ion with citrate complexes. these are subsequently recovered from the resin by 0.5m ammonium citrate eluent at ph 2.0. under optimized conditions, quantitative recovery was ...
A new process to leach and recover copper from solid waste using electric fields was designed. The leaching with electro migration is presented as an alternative to traditional leaching. Preliminary data indicate that the copper ion migration is facilitated by using the electrical potential difference; therefore applying a potential difference in the processes of leaching facilitates the remova...
The study was undertaken to estimate plasma copper and zinc in thirty-five depressed patients. Two blood samples were drawn from each patient, one before starting treatment and the second after recovery from depression. The results were compared with the thirty-five normal healthy individuals. The mean plasma copper in controls, depressed patients and in patients after recovery were 106.82, 122...
