to the limited processing capacity of a single shaking table,
a large number of tables are employed in plant operations.
This results in the need for a large area to house the shaking
table selection and the associated high production cost.
It can be concluded from the test work that the pro-
cessing of a Zn flotation tailings sample is quite efficient
when it is performed according to the proposed flowsheet.
A large proportion of tailings have been removed by des-
liming, reflux classifier, and flotation process, which sig-
nificantly reduces the yield from 45.31% to 12.75%. So
shaking table cleaning can be adopted to obtain high barite
grade, and table quantity can be reduced.
The step of barite cleaning is of considerable impor-
tance for what can be seen from Table 8 in the following
text that calculated based on the head ore, commercial
barite concentrates at a 7.30% yield, 92.75% barite con-
centration and 39.63% barite recovery was obtained. The
final tailings yield was further decreased from 45.31% to
38.01%. The tailings can be completely consumed by the
mine back filling operation, thereby realizing zero discharge
of tailings to surface ponds.
FULL-PROCESS TEST RESULTS
Figure 9 illustrates the whole process flowsheet and the test
results are summarized in Table 7.
It can be concluded from the test that processing of
ore using the proposed flowsheet is quite efficient for the
recovery of Pb, Zn, dolomite and Barite. Dolomite concen-
trates with a yield of 47.19% have been obtained at coarse
particle sizes, which can be sold locally as a raw material
