Embodiment 1

[0031] The raw material is the seaside placer of Yimeizhi mine in Australia, and the raw ore is magnetically separated to obtain the rough concentrate of zircon. 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%.

[0032] The beneficiation process adopts the method of pre-jigging classification-hydrocyclone classification-spiral chute gravity separation-shaking table gravity separation. See the process flow figure 1 . The steps are:

[0033] ⑴ Jigging gravity classification

[0034] Zircon coarse concentrate is obtained after the ore is magnetically separated, and ZrO in zircon 2 % content 45.58%, TiO 2 % content 5.28%. Zircon coarse concentrate is subjected to jigging separation, and the minerals are divided into three grades, namely coarse-grained and high-density minerals (+0.2mm), medium-grained and medium-density minerals (-0.2mm+0.12mm) And fine-...

Embodiment 2

[0047] The difference between embodiment 2 and embodiment 1 is:

[0048]The mass concentration of step (1) sieving ore feeding is 30%; step (3) the ore feeding concentration of the three products is 10% respectively, and the ore feeding amount is 1000kg (dry ore amount) / h; step (5) ore feeding The mass concentration is 10%.

Abstract

The invention provides a beneficiation process for the combined separation of zirconium ores with a hydrocyclone-spiral chute, which mainly includes jig gravity separation and classification, two-stage classification of a hydrocyclone, roughing in a spiral chute, sweeping in a spiral chute, and a shaking table. Scanning and other steps, and strictly control the key parameters. The invention adopts the double classification of pre-selection gravity and particle size, and realizes the separation of zircon and ilmenite through the combined action of gravity, centrifugal force and other force fields. This method recovers zircon products comprehensively, and the comprehensive recovery rate of zircon products can be increased to more than 96%, and in the recovery and utilization of tailings, the recovery rate of ilmenite is increased by 25-35%. The recovery rate reaches more than 92%, which has good economic benefits.

Description

technical field [0001] The invention belongs to the technical field of mineral processing, and in particular relates to a mineral processing process for combining a hydrocyclone and a spiral chute to separate zirconium-titanium ore. 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 decreasing day by day and ...
