Surface electrical conductivity. Conductive minerals discharge on the earthed roll and are thrown clear, non-conductors hold their charge, pin to the roll and are carried around to a separate outlet. It is the standard way to split conductors such as rutile and ilmenite from non-conductors such as zircon and monazite.
mtHTR
Precise electrostatic separation for cleaner conductive and non-conductive mineral streams.
Why it matters
Separate valuable minerals with similar physical properties by using differences in their electrical conductivity.
Features
A high-voltage corona and earthed rotating roll separate conductive particles from non-conductive material, with adjustable splitters controlling the product streams.
Problems it solves
Separate conductive and non-conductive minerals where conventional physical or magnetic separation alone cannot make the required cut.
Applications
Designed for mineral sands, rare earths, iron ore and tin duties, including separating conductive rutile and ilmenite from non-conductive zircon, monazite and garnet.
