Abstract The valorization of phosphate mine waste (PMW) in different fields has recently become attractive to many researchers. This review paper examines the potential use PMW as a raw material applications toward sustainable management strategies. Dewatering, recovery and heavy metals, building materials ceramics have been captured this paper. Based on origin deposit treatment during ore bene...
Selective solid-phase reduction of iron and phosphorus in oolite ores the Lisakovsky Ayat deposits was experimentally studied. Using X-ray phase analysis, composition initial samples after roasting determined. Goethite, magnetite quartz were found both deposits. Phosphorus ore deposit is form aluminum phosphate hydrophosphate, – as a component calcium hydrophosphate. Experiments on carried out ...
Rats fed a corn grit diet containing large amounts of ferric citrate absorb and deposit excessive amounts of iron in their livers. Undoubtedly various factors are involved in iron absorption, but these studies indicate that the low level of dietary phosphate was primarily responsible. The addition of phosphate salts to this diet has shown that the amount of iron deposited in the liver was inver...
The Siahrudbar deposit is located about 25 km southwest of Aliabad-Katool city in the Golestan Province, north of Iran. This deposit lies between the Triassic limestone (Elika Formation) and Jurassic sandstone (Shemshak Formation). Mineralogical studies indicate the presence of major minerals such as diaspore, hematite, anatase, kaolinite, and chamosite accompanied by minor minerals such as boe...
The application of geological controls in orebody evaluation and modelling is critical. Stratigraphic orebodies require more accurate location in space and better seam boundary definition. This is achieved by either modelling boundary surfaces of the orebodies or their thickness at specific points in 3D space. Structurally deformed stratigraphic deposits pose a very special problem in variograp...
Sponge remains have been identified in the Early Vendian Doushantuo phosphate deposit in central Guizhou (South China), which has an age of approximately 580 million years ago. Their skeletons consist of siliceous, monaxonal spicules. All are referred to as the Porifera, class Demospongiae. Preserved soft tissues include the epidermis, porocytes, amoebocytes, sclerocytes, and spongocoel. Among ...
Calcium phosphate-based (CaP) bioceramic materials are widely used in the field of bone regeneration, both orthopaedics and dentistry, due to their good biocompatibility, osseointegration osteoconduction. The formation CaP coatings on high-strength implant such as titanium alloys combines superior mechanical properties metals with osteoconductive materials. In this work, electrochemically assis...
