Embodiment 1

[0026] The raw material is the seashore placer of Yimeizhi mine in Australia. The raw ore is subjected to magnetic separation to obtain zircon rough concentrate. The raw ore contains 45.58% ZrO2 and 5.28% TiO2. The particle size distribution of zircon is extremely uneven, with +0.18mm accounting for 23.85%, -0.18mm+0.12mm accounting for 34.26%, and -0.12mm accounting for 41.89%. The distribution is extremely uneven, and the method of pre-grading - rough selection in spiral chute - sweeping in spiral chute - sweeping in shaking table is adopted. Such as figure 1 The process flow, the specific process parameters are:

[0027] (1) High frequency sieve classification

[0028] Zircon coarse concentrate is obtained after the ore is magnetically separated, and ZrO in zircon 2 % content 45.58%, TiO 2 % content 5.28%. The high frequency sieve is 6m 2 The double-layer screen, the length of the single-layer screen is 3 meters, the upper screen uses 0.20mm mesh, and the lower screen...

Embodiment 2

[0041] The difference between this embodiment and Example 1 is that in step (1), the screening feed concentration is 5%, and the processing capacity is 1 ton / hour; in step (2), the feed concentration of three grain grade products is 20% respectively. %, the amount of ore feeding is 2 tons / hour (dry ore amount); in step (4), the stroke of the shaking table is 0.8cm, and the number of strokes is 300 times / min.

Embodiment 3

[0043] The difference between the present embodiment and embodiment 1 is that in step (3), the ore feeding concentration of three particle grade products is respectively 20%, and the ore feeding amount is 2 tons / hour (dry ore amount); in step (4), The stroke of the shaker is 1.2 cm, and the stroke frequency is 500 times / min.

Abstract

The invention provides a high-frequency vibrating screen and spiral chute combined mineral separation process for separating zircon-titanium ore. The mineral separation process comprises the steps ofconfiguring the concentration of a zircon rough concentrate raw material to be 5-10%, using a high-frequency vibrating screen to sieve the zircon rough concentrate raw material into three particle grades, namely +0.18 mm, +0.12 mm-0.18 mm and -0.12 mm, and obtaining ores of three grades; respectively feeding the ores of the three grades into different spiral chutes for roughing to obtain zircon concentrates 1-3 and ilmenite rough concentrates 1-3 respectively; respectively feeding the ilmenite rough concentrates 1-3 into the different spiral chutes again for spiral chute scavenging, and obtaining zircon concentrates 4-6 and ilmenite rough concentrates 4-6 respectively; finally, respectively feeding the ilmenite rough concentrates 4-6 into a shaking table for shaking table scavenging, and obtaining zircon concentrates 7-9 and ilmenite rough concentrates 7-9; combining the zircon concentrates 1-9 to obtain a zircon product; and combining the ilmenite rough concentrates 7-9 to obtain an ilmenite product. By means of the high-frequency vibrating screen and spiral chute combined mineral separation process for separating the zircon-titanium ore, the obtained zircon and ilmenite are highin grade and recovery rate.

Description

technical field [0001] The invention relates to the technical field of mineral processing, in particular to a mineral processing technology for separating zirconium-titanium ore in combination with a spiral chute of a high-frequency vibrating screen. Background technique [0002] Seaside placer is a very important deposit in the mineral resources of Hainan, my country. In addition to rich ilmenite reserves, this kind of deposit is accompanied by zircon and monazite with huge reserves. There are also many foreign resources of this kind in other places, such as Australia, Malaysia, the United States, South Africa, Brazil, India and so on. [0003] At present, many zircon and ilmenite beneficiation plants in my country use shaking table to separate ilmenite in zircon concentrate. Bed sorting is very difficult, and the processing volume is small, and the time cost is high, resulting in difficulty in capital turnover. As my country's zirconium and titanium resources are decreasi...
