The invention relates to a laboratory ore grinding method for an unevenly inlaid gold ore. The unevenly inlaid gold ore is ground by adopting a laboratory mill. The laboratory ore grinding method comprises the steps that ore grinding is conducted, ground gold ore is added into a first laboratory mill for conventional ore grinding, and ground to be -75 [mu]m accounting for 80%, and then dischargingis conducted to obtain first ore pulp; screening is conducted, a standard screen of 38 [mu]m is added to screen the first ore slurry, and the first ore slurry is screened into size fractions of +38 [mu]m or above and size fractions of -38 [mu]m or below; regrinding is conducted, the size fractions of +38 [mu]m or above are added into a second laboratory mill for regrinding, and ground until the conventional standard screen of 75 [mu]m is used for screening out size fractions of +75 [mu]m accounting for 10% of raw ore, and then discharging is conducted to obtain second ore pulp; and mixing isconducted, the size fracti
