Fine-grained rutile ore flotation method

Red fine gold ore flotation step rougher tailing method. The invention relates to a fine-grained rutile ore flotation flotation selective tailing technology, belonging to the technical field of mineral processing engineering. The invention firstly utilizes aluminum sulfate to inhibit the characteristics of rutile and different degrees of activated silicate minerals, and uses sodium oleate as a collector to reverse flotation of rutile to achieve effective desilting during reverse flotation; reuse of sodium fluorosilicate and carboxy Synergistic action of methylcellulose and residual aluminum sulfate in the pulp, combined to inhibit gangue minerals, using lead nitrate ( or lead acetate ) as rutile activator, sodium hydroxycitrate and benzyl phthalic acid ( or styrenephosphonic acid ) a combination of flotation collector rutile, i.e., "first reverse flotation inhibiting rutile, rutile reactivation flotation" and "flotation step" to achieve fine rutile rougher tailing. The method has high rutile enrichment ratio, high recovery rate and thorough tailing, which can greatly reduce the ore beneficiation cost of rutile.

Coalescence &Separation Filter Elements

Describe:

The coalescence separation filter element is generally cylindrical in shape, and the coalescence separation filter element is used in the oil-water separation system, mainly separating the oil-water mixture, suspension solution, emulsion solution, etc. The application flow of coalescence separation filter in the system can be divided into solid-liquid separation-demulsification-coalescence-separation. In the system, the number of Coalescence Filter and separation filter is better than that of 3:1, the effect of coalescence is good and the separation speed is fast.

Principle and characteristics:

The surface treated glass fiber or polyester fiber is mainly used as the coalescence medium. The structure of the Filter Material is 0.1 Î¼ m by special design. The filter medium has good coalescence performance. Working process: after the emulsified oil enters the coalescence separator, it first enters the inner filter core from inside to outside, and the small liquid droplet in the dispersed phase changes from small to large. Finally, it falls off on the surface of the coalescence filter core and completes the coalescence process. In the process of flow separation, the larger water drops sink into the sink by gravity, and the small water droplets flow along with the oil to separate the filter elements. The separation filter has hydrophilic effect to block the passage of water. Small water beads collide to form large water droplets, which then settle into the sink again, thus dehydrating the oil.

Different packing sizes should be selected according to different oil-water systems: the smaller the packing size, the larger the specific surface area per unit mass and the larger the contact area with droplets. As a result, the performance of the coalescence filter element is enhanced. Therefore, it is suggested that the separation efficiency of coalescence filter should be taken into account when choosing fiber size, and the pressure drop should be taken into account at the same time.

Range of applications
