摘要
对含金锑砷多金属硫化矿矿石经混合浮选后，混合精矿用碳酸钠（Ｎａ＿２ＣＯ＿３）调节矿浆ｐＨ至１０左右，添加硫化钠（Ｎａ＿２Ｓ）作辉锑矿抑制剂，浮选砷（金），可获得含锑４９．４４％，砷０．４４％，回收率εＳｂ８０．８５％的锑精矿和含砷１０．９６％，金７９．９４ｇ／ｔ，回收率ε＿Ａｓ７７．９８％，ｅ＿Ａｕ６８．７９％的砷（金）精矿，试验表明，碳酸钠和硫化钠的使用比例以３：１最好。
Following flotation of complex sulfide ore containing gold, antimony and arsenic,the pH value of the bulk concentrate pulp is conditioned to 10 or so with the help of sodium carbonate, then adding sodium sulfide(Na_2S)as inhibitor of stibnite.In this way, the antimony and arsenic concentrates can be obtained. Of the two type concen traies, the former contains antimony,49.44%,arsenic 0.44 % with 80.85% recovery rate of antimony achieyed, the latter contains arsenic 10.96 %,gold 79.94g/t with 77.98% and 68.79% recovery rate of arsenic and gold achieved respectively.
