When the minimal renal threshold for blood hemoglobin is exceeded there is observed a deposit of iron staining pigment in the epithelium of the renal convoluted tubules. At a certain point this epithelium cannot take up more hemoglobin and this coincides with the minimal renal threshold level. When the injections of blood hemoglobin are kept below the minimal renal threshold level we note a com...

The objective of this research is to determine all processes in the magmatic evolution and related hydrothermal activities that created the volcanic rocks and associated ore-forming systems of the Bafq ‎mining district. Several iron oxide-apatite (IOA) deposits were investigated in this area with a focus on the Sechahun ore deposit. The Bafq ‎mining district is well known for hosting significan...

different types of iron oxides deposits have been identified along the khaf – dorouneh volcanic and plutonic belt in north east of iran. kuh-e-zar is one of these ore deposits known as fe- oxide gold deposit. the main purpose of this paper is to detect and discriminate the iron oxide minerals in this area based on the etm+ data. data processing has been done by envi (environment for visualizing...

introduction there is an iron mining complex called shahrak 60 km east of takab town, nw iran. the exploration in the shahrak deposit (general name for all iron deposits of the area) started in 1992 by foolad saba noor co. and continued in several periods until 2008. the shahrak deposit comprising 10 ore deposits including korkora-1, korkora-2, shahrak-1, shahrak-2, shahrak-3, cheshmeh, golezar...

The scope of this paper and presentation is to address the properties and benefits of the alkaline cyanide-free zinc deposit as a base coating for paint and powder coating applications. The deposition structure and process characteristics for alkaline cyanide-free zinc plating will be evaluated and compared to acid chloride zinc plating, zinc phosphating and iron phosphating. Salt spray testing...

alteration was ohserved along minor subsidiary faults in the northwest and northeast parts of Iron Range Mountain. The main Iron Range deposit consists of the segment of the ault containing the richest iron mineralization and underlies the northern half of the ridge which makes up Iron Range Mountain. This area extends northward onto the Grassy Mountain sheet (82FB). The area of m...

introduction iron-apatite ore deposits well known as kiruna iron type formed in association with calc-alkaline volcanism from proterozoic to tertiary (hitzman et al., 1992). liquid immiscibility in an igneous system was proposed to explain the formation of the iron oxides accompanying apatite in mineralized zones (förster and jafarzadeh, 1994; daliran, 1999). the mode of ore formation however, ...
