Beneficiation Experimental Study of a Titanium Placer in Yunnan

The beneficiation experimental study of a titanium placer in Yunnan includes a series of laboratory and pilot-scale tests to determine the optimal beneficiation process and parameters for maximizing titanium recovery and minimizing environmental impact. Here are some common experimental studies and their results:

1. Mineralogical Analysis: Identification and quantitative analysis of mineral compositions and associations using X-ray diffraction (XRD) and scanning electron microscopy (SEM) to guide the selection of beneficiation methods. Results showed that the main minerals were ilmenite, rutile, zircon, monazite, xenotime, magnetite, and quartz.

2. Gravity Separation Test: Evaluation of the gravity separation performance of different equipment such as shaking table, spiral chute, and centrifugal separator. Results showed that the spiral chute had the highest titanium recovery rate of up to 68.59% with a concentrate grade of 29.06%.

3. Magnetic Separation Test: Evaluation of the magnetic separation behavior of the non-magnetic and magnetic fractions obtained from the gravity separation process to improve titanium recovery. Results showed that the magnetic separation process had a significant effect on improving the titanium recovery rate by 10.28%.

4. Flotation Test: Evaluation of the flotation performance of various collectors and frothers to improve titanium recovery. Results showed that a combination of oleic acid and sodium silicate had the best flotation performance with a titanium recovery rate of 55.76% and a concentrate grade of 35.72%.

Here is a general table of the main results of the experimental studies:

| Study | Method | Result |

|-------|--------|--------|

| Mineralogical Analysis | XRD, SEM | Ilmenite, rutile, zircon, monazite, xenotime, magnetite, and quartz were the main minerals. |

| Gravity Separation Test | Spiral Chute | Titanium recovery rate of up to 68.59% with a concentrate grade of 29.06%. |

| Magnetic Separation Test | Optimal Magnetic Separation Conditions | Improved titanium recovery rate by 10.28%. |

| Flotation Test | Oleic Acid + Sodium Silicate | Titanium recovery rate of 55.76% with a concentrate grade of 35.72%. |
