The invention provides a crushed ore sample holder with annular pressure and an ore sample column leaching pretreatment method. Relates to the technical field of crushed ore sample leaching simulation tests, and comprises a pressure applying cavity, an ore sample container and an anti-swelling cover, a liquid outlet channel is arranged on the ore sample container, a test cavity is arranged in the ore sample container, the circumferential side wall of the test cavity is made of an elastic material, the test cavity is arranged in the pressure applying cavity, and the anti-swelling cover is arranged in the pressure applying cavity. The side wall of the test cavity is covered with an anti-expansion cover, and the anti-expansion cover is provided with a uniform water-permeable and air-permeable structure and can resist outward expansion of the circumferential side wall of the test cavity. According to the scheme provided by the invention, the defects that confining pressure cannot be applied to a metal sand fillin
