System and method for solubilising in an aqueous medium elements contained in a sulfide ore concentrate

A system to use an aqueous means to generate solubility on components contained in a sulphurous ore concentrate containing iron, cobalt, nickel, copper, and platinum group metals comprising:

• a) a blending device made up of:
• a first chute containing the ore concentrate (1),
• a second chute containing carbon containing material (2),
• wherein each one of the first chute and the second chute has a worm gear,
• a first deposit (4) for solid blends,
• a second deposit (5) for adding sulphuric acid, a reservoir for sulphuric acid concentrate (7), and
• an injector (6) for spraying sulphuric acid onto the solid blend;
• b) a device for chemical reactions made up of:
• a first microwaves power generator (8), equipped with flow, pressure & temperature sensors (26) a second microwaves power generator (13),
• a first multi mode chamber (14), and
• a second multi mode chamber (15),
• wherein each multi mode chamber has one or more conveyor belts (9),
• and also, each multi mode chamber has one or more modifying devices for positioning solid particles (10);
• c) external disaggregators (11);
• d) an additional blending device suitable to make a blend made up of sulphuric acid concentrate, with minimum purity of 96%, and gaseous oxygen applied at stoichiometric pressure, equipped with accessories to control its internal behavior, including pressure and temperature sensors, designed with opening devices for installing components aimed to facilitate contact between acid and oxygen, and other components facilitating input/output of materials associated to this blend preparation, to be sprayed onto the material unloaded by the external disaggregators (12);
• and) a sulphurous gases collecting device comprising:
• a hood for extracting sulphurous gases (16), and
• a water trap for sulphurous gases (17), containing industrial water (27);
• f) a device for extracting the elemental sulphur (18);
• g) an agitation tank (22);
• and
• h) a clarifying tank (23).
