摘要
针对龙头山金矿选冶工艺流程存在的问题，为提高回收率和处理能力对原流程进行了技术改造。技改后的工艺流程适宜矿石性质，畅通稳定，选矿回收率由技改前的８７－５５％提高到９２－１５％，处理能力由原设计的１００ｔ／ｄ提高到２００ｔ／ｄ，选冶成本由技改前１４５－５４元／ｔ降低到１０５－７０元／ｔ，较技改前累计取得了７４２－６６万元的显著经济效益。
The reforms of the original process flow of ore dressing and smelting in Longtoushan Gold Mine were made in order to overcome the problems in it and improve its treatment capacity.It showed that the reformed process flow was unblocked.stable and adaptable to ore property.As a result,the recovery rate of ore dressing improved from 88.55% to 93.16%,the treatment capacity improved from 100t/d of design to 200t/d,the unit treatment cost decreased from $145.54 to $105.90 and the accumutative total of economic benefit reached $7.4266 millions.
