Embodiment 1

[0022] Embodiment 1: A process for recovering low-grade sphalerite and cassiterite minerals from copper beneficiation tailings, which mainly includes three processes of graded desliming, zinc-sulfur mixed separation-separation, and shaking table tin selection. The specific steps are as follows :

[0023] First, the staged desliming process (see image 3 ), transport the copper beneficiation tailings to the cyclone group A for grading, the type of the cyclone group A is Ф250mm, the ore feeding pressure is 0.06MPa, the ore feeding concentration is 20%, and the output of the cyclone group A is graded There are two products of sand settling and overflow; the overflow of cyclone group A is transported to cyclone group B for desliming. The model of cyclone group B is Ф75mm, the feeding pressure is 0.20MPa, and the feeding concentration is 8 %, to obtain two products of sand settling and overflow, the overflow is mainly -10μm grain size sludge, which can be thrown out, the sand sett...

[0024] Embodiment 2: A process for recovering low-grade sphalerite and cassiterite minerals from copper beneficiation tailings, which mainly includes three processes of graded desliming, zinc-sulfur mixed separation-separation, and shaking table tin selection. The specific steps are as follows :

[0025] First, the staged desliming process (see image 3 ), transport the copper beneficiation tailings to the cyclone group A for grading, the type of the cyclone group A is Ф250mm, the ore feeding pressure is 0.10MPa, the ore feeding concentration is 30%, and the output of the cyclone group A is graded There are two products of sand settling and overflow; the overflow of cyclone group A is transported to cyclone group B for desliming. The model of cyclone group B is Ф75mm, the feeding pressure is 0.25MPa, and the feeding concentration is 13 %, to obtain two products of sand settling and overflow, the overflow is mainly -10μm grain size sludge, which can be thrown out, the sand set...

Embodiment 3

[0026] Embodiment 3: A process for recovering low-grade sphalerite and cassiterite minerals from copper beneficiation tailings, mainly including three processes of graded desliming, zinc-sulfur mixed separation-separation, and shaking table tin selection. The specific steps are as follows :

[0027] First, the staged desliming process (see image 3 ), transport the copper beneficiation tailings to the cyclone group A for grading, the type of the cyclone group A is Ф250mm, the feeding pressure is 0.08MPa, the feeding concentration is 25%, and the output of the cyclone group A is graded There are two products of sand settling and overflow; the overflow of cyclone group A is transported to cyclone group B for desliming. The model of cyclone group B is Ф75mm, the feeding pressure is 0.23MPa, and the feeding concentration is 10 %, to obtain two products of sand settling and overflow, the overflow is mainly -10μm grain size sludge, which can be thrown out, the sand settling of cycl...

Abstract

The invention relates to the field of mineral separation, in particular to a mineral separation technology for economically and efficiently recovering low-grade marmatite and cassiterite minerals from copper separation tailings. The mineral separation technology mainly comprises the three steps of classification desliming, zinc and sulfur mix-floatation and separation, and tin separation with a shaking table. The effect of economically and efficiently recovering the low-grade marmatite and cassiterite minerals in the copper separation tailings can be realized.

Description

technical field [0001] The invention relates to the field of mineral processing, in particular to a beneficiation process for economically and efficiently recovering low-grade sphalerite and cassiterite minerals from copper beneficiation tailings. Background technique [0002] In recent decades, my country's development of mineral resources has been intensive, and mineral resources with high grade and good selectability have gradually decreased, and the sustainable supply capacity of mineral resources has declined. For the national conditions of our country with a large population and relatively insufficient resources, the comprehensive utilization of mineral resources, especially the recycling of associated ores, has attracted more and more attention. At the same time, how to economically and efficiently recover low-grade mineral resources is also a challenge in the mineral processing field. A big problem. [0003] For the associated low-grade sphalerite and cassiterite mi...
