Ore pulp treatment method and pressurized oxidation method for molybdenum concentrate

The invention discloses an ore pulp treatment method and a pressurized oxidation method for molybdenum concentrate, and belongs to the technical field of molybdenum concentrate pretreatment and molybdenum smelting. The ore pulp treatment method comprises the following steps that firstly, dextrin and tannic acid are added into water to be fully dissolved, and a dextrin solution and a tannic acid solution are obtained; 2, the molybdenum concentrate powder is added into water to be stirred, and ore pulp is obtained; step 3, adding a dextrin solution and a tannic acid solution into the ore pulp, and fully stirring to obtain slurry; fourthly, the slurry obtained in the third step is heated to the set temperature and stirred, and dextrin and tannic acid make full contact with the molybdenum concentrate; 5, the temperature of the slurry is kept, activated carbon particles are added to adsorb and remove hydrocarbon oil on the surface of the molybdenum concentrate, and stirring is conducted continuously in the whole p
