Abstract
A method for processing a heavy mineral concentrate obtained from froth treatment tailings to produce a zirconium concentrated product, including subjecting the heavy mineral concentrate to froth flotation, subjecting a flotation product to initial gravity separation, subjecting an initial gravity separation product to primary dry separation, subjecting a primary dry separation product to finishing gravity separation, and subjecting a finishing gravity separation product to finishing dry separation to produce a finishing dry separation product as the zirconium concentrated product.
Claims34
A method for processing a heavy mineral concentrate obtained from froth treatment tailings to produce a zirconium concentrated product, wherein the froth treatment tailings result from a process for recovering bitumen from oil sand, wherein the process for recovering bitumen from oil sand is comprised of producing a bitumen froth from the oil sand, wherein the process for recovering bitumen from oil sand is further comprised of separating the froth treatment tailings from the bitumen froth in a froth treatment process, the method comprising:
- (a) subjecting the heavy mineral concentrate to froth flotation to selectively recover zirconium in order to produce a flotation product;
- (b) subjecting the flotation product to initial gravity separation to selectively recover zirconium in order to produce an initial gravity separation product;
- (c) subjecting the initial gravity separation product to primary electrostatic separation to selectively recover zirconium in order to produce a primary electrostatic separation product;
- (d) subjecting the primary electrostatic separation product to primary magnetic separation to selectively recover zirconium in order to produce a primary magnetic separation product;
- (e) subjecting the primary magnetic separation product to finishing gravity separation to selectively recover zirconium in order to produce a finishing gravity separation product;
- (f) subjecting the finishing gravity separation product to finishing electrostatic separation to selectively recover zirconium in order to produce a finishing electrostatic separation product;
- and
- (g) subjecting the finishing electrostatic separation product to finishing magnetic separation to selectively recover zirconium in order to produce a finishing magnetic separation product as the zirconium concentrated product.
