摘　　要：提出材料环境负荷效用指数的概念 ,建立黄金提取方法的环境负荷定量评价模型 ,对现有 7种不同提金方法的资源消耗负荷、能源消耗负荷、废水和废气污染负荷等分别进行了计算和综合评价。结果表明 ,氰化法生产工艺环境负荷最大 ,改性石硫合剂法生产工艺环境负荷最小 ,符合客观实际 ,评价结果可靠。方法计算简便、评价客观、评价容错能力强。The quantitative assessment model on the environmental load for various gold leaching methods is established by using the material environmental utility indexes And the existent 7 techno1ogies of gold production including developing ones (cyanide and six sulfur bearing gold leaching reagents) are assessed respectively by the calculation and evaluation of the resources consumption, energy consumption, and the pollution load of wasted waters and gases The results indicate that the environmental load of the cyanide leaching process is the heaviest, and the ML process is the weakest among the seven processes, it is consonant with the realistic situation, so the results are reliable In the assessment, the calculation is convenient, the evaluation is objective and with high capacity for error proof, and the results are highly reliable
