Abstract: In order to improve the development and utilization efficiency of a spodumene mine，aim‐ ing at the problems of complex mineral composition and difficult separation of the spodumene，based on the study of ore properties，a comparative test of flotation process under desliming and non-desliming condi‐ tions is carried out.The results show that under the conditions of grinding fineness of -0.074 mm 70%，dos‐ age of adjusting agent sodium carbonate + sodium hydroxide（1 000+300）g/t，dosage of activator magne‐ sium chloride 150 g/t，dosage of combined collector BK452A+BK452B（1 200+800）g/t，without deslim‐ ing，spodumene concentrate with Li2O grade of 5.71% and Li2O recovery of 85.52% is obtained by closed�circuit test with one roughing，three cleaning and one scavenging process，which provides technical support for the efficient development of this kind of ore.

Key words: spodumene ore, non-desliming, combined collector
