The invention discloses a method for leaching arsenic containing carbon gold ore through pyrolusite in a high pressure and non-cyanidation manner. The method comprises the following steps that firstly, the arsenic containing carbon gold ore is mechanically activated; secondly, pyrolusite ore is taken and subjected to acidification through sulfuric acid to serve as a leaching agent, the leaching agent is added in the arsenic containing carbon gold ore treated in the first step, and first-section leaching is conducted; thirdly, after first-section leaching is conducted, solid-liquid separation is conducted, first-section leaching liquid and leaching slag are obtained, and the leaching slag is washed through weak-acid washing liquid; fourthly, cyanuric acid salt obtained after sulfuric acid acidification serves as a leaching agent, the leaching agent is added in the washed leaching slag obtained after acid acidification, and second-section leaching is conducted; fifthly, after second-section leaching, solid-liquid separation is conducted, and after washing is conducted through deionized water, second-section leaching liquid and tailings slag are obtained; and sixthly, the first-section leaching liquid and the second-section leaching liquid are subjected to separation and purification treatment. According to the method, effective and comprehensive utilization of carbon, sulfur andarsenic in the arsenic containing carbon gold ore can be achieved, the recycling rate of gold, iron, manganese, sulfur, arsenic and other valuable elements reaches 95% or above, and the resource utilization rate is high.
