由广东省有色金属总公司汕头有色金属公司主持召开的厚婆坳东区V40矿体选矿试验技术鉴定会,于1985年12月5日至7日在昆明召开。参加会议的有来自广东、云南两省九个单位的31名代表。会上昆明冶金研究所详细介绍了V40矿体的物质组成研究、选矿工艺试验和尾矿水试验情况,根据矿石中硫化物与脉石共生情况比较简单,硫化矿物之间关系密切,部份锡石结晶粒度细的特点,采用了硫化物混合分离浮选产出铅精矿及铅锌混合精矿,浮选尾矿重选产出锡精矿的流程,所获得的总回收率指标分别过铅86.05％、锌76.45％、银71.91％、
The Appraisal Technical Appraisal Meeting of V40 Ore Beneficiation Test of Houpo-Voxi District hosted by Shantou Nonferrous Metals Corporation of Guangdong Nonferrous Metals Corporation was held in Kunming on December 5, 1985. There were 31 delegates from nine units in Guangdong and Yunnan provinces attending the conference. Metallurgical Institute of Kunming Metallurgical Institute detailed the V40 ore body composition studies, beneficiation process tests and tailings water test, according to ore in the gangue sulfide and gangue situation is relatively simple, close relationship between sulfide minerals, part of the tin Stone fine grain size characteristics, the use of sulfide mixed separation flotation of lead concentrate and lead-zinc concentrate, flotation tailings re-election process of tin concentrate, the total recovery indicators were obtained over 86.05% lead, 76.45% zinc, 71.91% silver,
