The invention relates to the technical field of titanium dioxide production and specifically relates to an ore feeding method applied to a titanium dioxide acidolysis procedure of a sulfuric acid method. The ore feeding method is a process in which titanium ore powder is fed into an acidolysis pot to be evenly mixed with sulfuric acid and comprises the steps: (1) calculating out a mixing proportion between sulfuric acid and titanium ore powder and determining a feeding amount A of the sulfuric acid; (2) introducing the sulfuric acid of one third to two thirds of the A into the acidolysis pot;(3) starting an air blowing system at the bottom of the acidolysis pot and starting an air suction system communicated with the top of the acidolysis pot and a spray device arranged on an air suctionpipe of the air suction system; (4) then starting a quantitative feeding device and evenly feeding titanium ore powder into the acidolysis pot. The method disclosed by the invention has the advantagesof low loss, low pollution, low fault rate and easiness in operation.
