With the addition of this fully automated, four-stage flotation lab circuit, Eriez reportedly
provides detailed analysis
of most flotation circuit configurations using laboratory
equipment ranging from grinding mills to bench-top
and continuous conventional and
column flotation cells.
Eriez Flotation Division (EFD) has commissioned
a fully automated, four-stage
lab-scale column circuit for flotation
testing on sulfide and industrial minerals.
Operating parameters such as air
flow rate, wash water flow rate, reagent
addition rates and pH level are regulated
using a programmable logic controller
(PLC). The flotation circuit can be altered
to accommodate multiple circuit configurations
ranging from one (i.e. rougher)
to four (i.e. rougher-scavenger-cleaner-
cleaner) unit operations, dependent
upon the characteristics of the feed ore.
The circuit is also capable of incorporating
recirculating loads. The automated
circuit can be utilized to conduct steadystate
column flotation tests at feed rates
of up to 15 kg/h.
EFD said it can provide detailed analysis
of most flotation circuit configurations
using laboratory equipment ranging from
grinding mills to bench-top and continuous
conventional and column flotation
cells. Typical tests range from exploratory
batch testing to the evaluation of multistage
flotation circuits. According to the
company, its analytical lab — including
an XRF (X-Ray Fluorescence), ICP-OES
(Inductively Coupled Plasma Optical
Emission Spectrometry), sulfur analyzer
and laser particle size analyzer — can
conduct in-house assays and improve
turnaround time on testing.
