Physical and Chemical Beneficiation of the Egyptian Beach Monazite

The Egyptian black sand deposits are present either as beach sediments or in the form of coastal sand dunes. This method has the advantage that the initial stage does not disrupt the procedure of rutile and zircon separation. However, the monazite rich fraction can not be concentrated to a salable grade solely by magnetic andseparation, a process that is controlled by the mineralogical characteristics of the deposit. Over the last few decades systematic work on the beach sand deposits of Sri Lanka has been carried out to study their distribution and mineralogy by the Geological Survey Department of Sri Lanka [8].

Air Tabling of Beach Sand Non-Conductors for Zircon Recovery

Unique ID: P_PROC1962_0960. Air tabling of zircon-rich non-conductor products containing quartz enables most of the fine quartz present to be rejected without a markedloss of zircon. The coarser quartz in the air table feed can be separated from the zircon by screening one or more air table products, the oversize products containing most of the100TPH beach sand processing plant.
