Mixed vulcanization-yttria ore beneficiation process

Beneficiation plant using hand-selected - re-election - flotation - re-election process

First, crushing and hand selection

1. The crushed mine is a two-stage closed circuit process. The maximum mass of the ore mine is 400 mm, which is lifted into the coarse ore bin of the concentrator by the hoist and fed into the first 600*900mm jaw crusher by the electromagnetic vibrating feeder. The ore is crushed to -150mm, and is washed by 1230 double-layer vibrating screen and sieved into three grades: -150~30mm granular ore is again screened and hand-selected, and -28~18mm grade ore enters the second stage and is broken. All of them are crushed to -18mm, de-sludged by a spiral classifier, and returned to the fine mineral storage tank for storage. The slime enters the thickener and is dehydrated and concentrated, and then separately subjected to flotation treatment.

2, hand-selected for two-stage operation, using the forehand selection to select the finished sulfur-oxygen-rich strontium concentrate and lean concentrate, and the lean concentrate is broken into the second closed-circuit crushing system. The hand-selected waste rock was transported to the waste rock yard by a dump truck.

Second, re-election and grinding

1. Re-elect the crushed and hand-selected ore for two-stage sorting. The first stage is divided into three-stage jigs (-18+8, -8+2, -2+0mm), and the jigging is carried out after the rod grinding (-4 -0mm) all obtained sulphur-oxygen mixed cerium concentrate. The second jigging tailings entered the ball mill.

2. Grinding rod mill is used to process -18+8, -8+2 mm two-stage jigging tailings. The ball mill is used to treat the second jigging tailings, and the finely ground products are then used to recover the sulfide products by flotation. There is also a billiard mill for grinding fine concentrates.

Third, flotation

The second stage of the jigging tailings is subjected to closed-circuit grinding and flotation of the strontium sulfide minerals. The flotation process is performed by one rough selection, one selection and one sweep.

Fourth, shaker re-election

Used to recover cerium oxide minerals in flotation tailings.

In addition, the plant also uses a flotation-re-election joint process to treat primary and secondary strontium slime.

Dot Peen Marking Machine

Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
Notable Characteristics:
Cost effective
Requires no consumables
High speed accuracy
Will mark any material (including hardened steel)

Compressed air is not required.
