Problems solved by technology

Judging from the density values ​​of the three minerals, rutile and omphacite can be separated better by gravity separation, but the density difference between rutile and garnet is small, and gravity separation is difficult to separate

Embodiment Construction

[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] see figure 1 , the combined production process of rutile ore in the present invention is partly graded ore dressing, comprising the following steps:

[0058] a. Grinding and classification

[0059] Grind the rutile raw ore with a 200×240XMB-67 rod mill, and sieve it with a 0.3mm sieve to obtain ore with a particle size of ≤0.3mm; in the grinding and grading products, the content of 200 mesh is 27.55%, and the upper limit of the particle size is 0.3mm .

[0060] b. Weak magnetic separation

[0061] Use XCRS-74 type Φ400×300 drum-shaped wet weak magnetic separator (separation magnetic field is 1450Oe) to carry out weak magnetic ore separation on the ore with a particle size of ≤0.3mm obtained in step a to separate the secondary iron concentrate, and the rest of the ore enters the next step. step;

[0062] c. Primary strong magnetic ...

Abstract

The invention relates to a rutile ore part size fraction benefication joint production process. The joint production process comprises the steps of part size fraction magnetic separation, reselection, magnetic separation, desliming and grading, and flotation in sequence, so that the limit of only recovering rutile or comprehensively recovering garnet and rutile can be broken, and three main minerals including rutile, garnet and omphacite in the ore can be recovered comprehensively. By adopting the process, the rutile concentrate with TiO2 being in 90% grade and garnet and omphacite concentrate with purity being 88% can be obtained, the recovery rates of TiO2, the rutile, garnet and omphacite are 67.44%, 77.95%, 81.50 and 71.18%. Test results show that the main mineral resources in raw ores can be reasonably and effectively utilized with low flotation cost.

Description

technical field [0001] The invention relates to an ore dressing process, in particular to a combined production process for rutile ore partial particle size separation and beneficiation. Background technique [0002] The quantitative results of the main minerals of eclogite-type rutile ore are shown in Table 1: [0003] Table 1 [0004] mineral rutile garnet Omphacite Ilmenite other Content (%) 4.90 56.91 37.19 ＜1 ＜1 [0005] However, it is very difficult to separate the above components from rutile ore. From a physical point of view. [0006] The above-mentioned components have different magnetic properties and different densities, and exist in different process particle sizes in the raw ore. [0007] The specific magnetic susceptibility coefficient of rutile is 14.55~11.17 10-6CGSMcm3 / g; the specific magnetic susceptibility coefficient of garnet is 96.32~73.40 10-6CGSMcm3 / g; the specific magnetic...
