The invention discloses a casting method of a large copper alloy lining. The casting method comprises the following steps that raw materials preparation is carried out; copper alloy melting is carriedout, specifically, the prepared materials are sequentially put into a high-efficiency pulverizer for crushing, the crushing time is 10-20min, the rotational speed of the high-efficiency pulverizer is3000-4500r/min, and metal powder is prepared, then the metal powder is put into a high temperature furnace, the temperature is adjusted to 1200-1300 DEG C, and metallic copper is melted to obtain a liquid copper alloy; copper alloy refining is carried out, specifically, the temperature of the high temperature furnace is again adjusted to 1300-1400 DEG C to remove molten slag on the surface, and finally, the temperature of the high temperature furnace is adjusted to 1480-1590 DEG C for refining the copper alloy; copper alloy lining die manufacturing is carried out; copper alloy lining die treatment is carried out; cent
