Abstract：Takingacertainarsenic-containing gold concentrateasanexample，agold extractionexperiment isconducted， andmulti-elementanalysis iscarriedoutontheoresample，theproceses of goldconcentrateroasting，roastingsandacid leaching，andleachingresidue cyanide leachingarestudied toobtainthemain processconditions，andthegoldleaching recoveryrateisobtainedundertheoptimal goldconcentrateroasting-acidleaching-cyanideconditions.Researchhas found that the decarbonization rate of high arsenic gold concentrate during roasting is 98.98% ，the desulfurization rate is 98.23% ， and the arsenic removal rate is 94.06% .Under the optimal process conditions，the leaching rate of gold is 93.87% ： Keywords： arsenic-containing gold concentrate; arsenic removal; acid leaching; gold extraction
