environmental effects of gol-e-gohar iron ore mine on groundwater of the area
gol-e-gohar iron ore mine of sirjan in southern part of iran is a large open pit that operates below the groundwater table and during mining operation, dewatering is required to prevent operation processes from flooding. current operation is going on by digging wells in or out of the pit and pumping to prevent flooding. as a result of the former dewatering operation a vast deep cone of depressi...
Notes on Myoglobin Preparation and Iron Content
Since the first description by Theorell (11) of a process of isolating and purifying myoglobin from horse heart by crystallization, several workers have succeeded in preparing myoglobin by Theorell’s procedure. Roche and Vieil (8) and Rossi and Aragona (9) have described methods less arduous than Theorell’s. Their methods, however, sacrifice yield to gain simplicity. We have developed a modific...

متن کاملThorium and Iron Content of Mine Dusts
The thorium content of mine dust collected at various locations along the drift to the SNO site has been measured with several techniques-direct counting, proton induced x-ray emission, x-ray fluorescence, and neutron activation analysis. The thorium content varies significantly, from a minimum of 4 ppm to a maximum of 24 ppm (from direct counting measurements). The average Th content of the si...
متن کاملIron Dynamics in Acid Mine Drainage
The oxidation of iron sulfides in mine wastes is the main cause of acidic, sulfate, and trace element-rich acid mine drainage (AMD). However, the suite of reactions that transform iron from one species to another is quite complex. A reasonable strategy for controlling AMD production is to identify and further slow the slowest, rate-determining step (RDS) in the overall process. This paper provi...
