Gold ore whose types of deposits are diverse and complex is the mineral assemblage of gold. With features of chalcophile affinity and high melting point, the gold ore includes conglomerate type, porphyry type, quartz vein type and volcanic rock type, etc.
Vanadium remains in the raffinate which is fed into a second solvent extraction circuit There vanadium in turn is extracted in the organic phase stripped with a 10 percent soda ash solution and precipitated with ammonium sulfate The ammonium metavanadate precipitate is filtered dried and calcined to V 2 O 5
containing much of the vanadium with low silica levels of two per cent Typical processing problems encountered are fine liberation size over grinding of the magnetite and variable response to magnetic separation resulting from the weathering profile Beneficiation options
The vanadium bearing magnetite ores are typically processed through either smelting producing vanadium bearing slag coproduction or the primary processing using a salt roasting and leaching operation called Salt Roast process Coproduction typically involves smelting magnetite oreconcentrate during which titanium slag is eliminated while vanadium and iron ore report together
Dec 19 2016 · VANCOUVER BRITISH COLUMBIA – December 19 2016 VanadiumCorp Resource Inc TSX “VRB” the “Company” is pleased to announce it has commissioned the preparation and process testing of massive magnetite from its 100 owned Lac Dore Vanadium Project in Quebec Canada
Titaniferous magnetite ore is mined in South Africa and China and processed for vanadium extraction Tianiferous magnetite ore is also processed in steelmaking operations in China Russia and South Africa A duplex BOF process in the steelmaking shop yields a vanadium rich slag that can be converted into V2O5 via hydrometallurgical processing
Vanadiumbearing materials are treated by means of several processes such as calcium reduction roastleach solvent extraction and ion exchange to recover vanadium either as metal ferrovanadium vanadium pentoxide or in the form of various chemicals
However little attention has been paid to vanadiumtitaniummagnetite VTM which is a magnetite containing iron and titanium as its main elements Lai et al 2018 Hence applications of VTM can offer an innovative research opportunity due to their superior performance in adsorption and catalytic degradation of pollutants Liuet al 2016
Indicative Vanadium Deportment In The Processing Of An evaluation of vanadium deportment in the processing of titaniferous magnetite titanomagnetite by roastleach vanadium primary production and electric furnace smelting vanadium coproduction processes was conducted
Vanadium can be recovered from titaniferous magnetite ore by either of two processes 1 precipitating a vanadium salt from a leach of ore roasted with salt or 2 precipitation from a leach of saltroasted vanadiumrich slag obtained by smelting the ore to make a vanadiumbearing pig iron which is then blown in a converter to make the vanadiumrich slag
Vametco employs the standard salt roast and leach process to produce a steelalloying vanadium carbon nitride product called Nitrovan The process involves the following stages Step 1 Crushing milling and magnetic separation to produce a magnetite concentrate with average grades of approximately 20 V 2 O 5 in magnetite
