This communication presents a model structure for the flotation recovery of middling particles (10–90% liberation). Fourteen datasets from literature were studied (galena flotation), which involved different systems and operating conditions. The responses allowed flexibility to be evaluated under range profiles. modelling results showed that galena can characterized by interaction between linea...
The Kuh-Sorbi barite-Pb ± Cu deposit, which is located southeast of Mashhad in Khorasan Razavi Province of Iran, occurs as vein, open space filling, host rock replacement, and cement within the fault breccia in the Upper Triassic Nayband Formation metamorphosed carbonate rock unit. This deposit contains of barite (80–85%) and galena (10–15%), with small amounts of chalcopyrite and quartz. Barit...
The study area is located about 25 km northwest of Takestan city, within Tarom-e-Sofla metallogenic belt. This area is covered by a widespread Eocene andesite to dasite volcanic rocks affected by Oligo-Miocene monzogranite to granodiorite igneous bodies which altered them to silicic, argillic zones as long as hypogene sulfide vein-veinlet mineralization (e.g. galena, sphalerite, pyrite, rare ch...
This study aims to investigate the content of lead in most frequently used brands of cosmetics products in Morocco.100 samples of kohl (kohl powder, galena, eye pencils and paste) were selected taken from large cosmetic stores in Morocco. And lead of them is analyzed using a Fast Sequential Atomic Absorption Spectrometer (SAAFS 240).The results showed that the concentrations of lead in kohl sam...
Nodushan Zn-Pb deposit at the western margin of Urumieh-Dokhtar volcano-plutonic belt resulted from granitoid intrusion into Eocene dacitic to andesitic rocks. Pyrite, sphalerite, galena and chalcopyrite are the main sulfide minerals. The chemical composition of sphalerites and pyrites indicates two different type of sphalerite (high Fe types demonstrating chalcopyrite disease and low Fe type) ...
