The invention discloses a treating method of an arsenious material. The processing method comprises the steps as follows: firstly carrying out normal pressure acid leaching on the arsenic material to make the copper, zinc, arsenic penetrate into the solution and also make the lead, gold and silver concentrate in the leaching slag; employing an extraction method to recover the copper from the leaching liquid rich in copper, zinc and arsenic; performing electrowining on the extracted and back-extracted leaching liquid to produce cathode copper or performing crystallization evaporation to produce cupric sulfate; reducing the extracted leaching liquid with sulfur dioxide to produce arsenic trioxide, then producing arsenic trioxide with purity of 99.9% after washing and drying; returning part of the reduced solution to the oxygen-rich leaching process and performing purification, precipitation and calcinations to obtain superfine zinc oxide powder; and returning oxygen-rich leaching residue containing lead, gold and silver to the recovery process for lead, gold and silver to produce electrolytic lead, silver, gold, antimony, bismuth products. According to the above method, the problem of environmental pollution caused by accumulation and storage of arsenic in the system is solved, and a variety of valuable metals are also comprehensively recycled, thereby improving the comprehensive utilization rate of resources and reducing the environmental pollution.
