This invention discloses a method for separating iron and titanium in high-iron, high-titanium vanadium-titanium magnetite, belonging to the field of mineral processing technology. To achieve the rational utilization of high-iron, high-titanium vanadium-titanium magnetite, this invention provides a method for separating iron and titanium in high-iron, high-titanium vanadium-titanium magnetite, comprising: crushing the high-iron, high-titanium vanadium-titanium magnetite to obtain crushed products; subjecting the crushed products to a first-stage grinding and magnetic separation to obtain magnetic concentrate 1 and tailings 1; subjecting magnetic concentrate 1 to a second-stage grinding and magnetic separation to obtain iron concentrate and tailings 2; combining tailings 1 and tailings 2 for screening and classification, and separately performing gravity separation on coarse and fine iron tailings to obtain titanium rough concentrate; finally, performing a three-stage high-intensity magnetic separation to obtain titanium concentrate. This invention employs a two-stage grinding and two-stage magnetic separation process, improving grinding efficiency, reducing over-grinding rate, separating tailings into coarse and fine particle sizes, improving gravity separation effect, and increasing yield while ensuring the grade of iron concentrate and titanium concentrate.

This invention relates to a short-process technology for enhanced separation of ilmenite, belonging to the field of mineral processing technology. The process includes three steps: (1) performing a roughing and scavenging flotation operation on the ilmenite feed material to obtain ilmenite flotation concentrate and flotation tailings; (2) performing acid pretreatment on the ilmenite flotation concentrate, followed by solid-liquid separation to obtain acid-pretreated ilmenite concentrate; and (3) performing a high-gradient strong magnetic separation roughing operation on the acid-pretreated ilmenite concentrate to obtain the final ilmenite concentrate. The process structure of this invention is simple and efficient. In the ilmenite beneficiation process, the addition of acid pretreatment can reduce heterogeneous agglomeration between ilmenite and gangue mineral particles, and the use of high-gradient strong magnetic separation can enhance the efficient collection of ilmenite, obtaining high-grade and high-recovery titanium concentrate, which fully solves the technical problem of the difficulty in recovering fine-grained ilmenite.

The utility model discloses a kind of mineral processing froth trough for flotation workshop, belong to mineral processing froth trough field, it includes froth trough main body, the side fixed connection of froth trough main body has connecting frame, the side fixed connection of connecting frame has protective shell, the side fixed connection of protective shell has connecting block, the side fixed connection of connecting block has motor;Through the cooperation of above each device, through the motor of being set and through connecting block symmetry fixed in protective shell, cooperate the adaptive design of protection shaft and motor output shaft, effectively reduce the shaking and vibration when motor operates, ensure that mixed plate stable agitator slurry.Meanwhile, the heat generated by the multiple heat dissipation openings on the protective shell can be dissipated in time, preventing the performance of the motor from being degraded due to high temperature, thereby ensuring the continuous and efficient operation of the mineral processing froth trough, improving the mixing and flotation of minerals, and ensuring the recovery rate and grade of mineral processing.
