Abstract

Abstract: In the grinding process of refractory iron ore containing siderite， the siderite is very easy to be slimed. A large number of fine siderite particles were adsorbed on the surface of gangue and useful minerals， which seriously deteriorates the following processing. In order to find out the essence and rules of adsorption and aggregation among the fine siderite，quartz and hematite in pulp， DLVO theory was applied to study the interaction mechanism between the fine siderite particle and the coarse quartz particle ， the fine siderite particle and hematite particle， the fine siderite particles，etc. The calculating results showed that the fine siderite particles are easily adsorbed on the surface of coarse quartz particles and hematite particles. The agglomeration phenomenon occurs between fine siderite particles and fine hematite particles， and doesn′t occur between the fine siderite particles.

Key words: fine siderite, quartz, hematite, adsorption and aggregation, DLVO theory
