Characteristics of gravity concentration: (1) The processable materials have expanded from lump/coarse to fine/slime grained materials, and the lower limit of fed ore particle size during ore separation is 20 μm; (2) in addition to gravity, other forces are employed in order to intensify the gravity concentration process, eg, the centrifugal RefferencesFinch,J, Introduction to mineral processing, MIME200 ROBurt, Gravity concentration technology, SME Mineral processing handbook, SME,1985 94 LOAD MORE SAMPLING FOR MINERAL PROCESSING Part 1 in a series INTRODUCTION TO SAMPLING FOR MINERAL PROCESSING Part 6 in a series 2 Introduction to Mineral Processing [PPTX Powerpoint]
Gravity concentration takes advantage of the high specific gravity range, 29–72, of the REE minerals, compared with 25–35 for most accessory gangue minerals 5 The technology is exemplified by the classic gold prospector’s pan, wherein worthless sand grains can be washed away from heavier gold particles by applying a gentle assessment and knowledge of expected mining and mineral pro cessing conditions 6311 Cost Estimation for Preliminary Feasibility O' Hara Alan T SME mining engineering handbook Vol 1 1992 ch 63 pp 405424 COSTS AND COST ESTIMATION 407 '"",= 720 TO3 for gravity concentration of iron ores (6319) (6320)COSTS AND COST ESTIMATION Chapter NUBE MINERA
