Embodiment 1、2、3

[0029] Embodiments 1, 2, and 3 merge the tables as follows according to the experimental situation:

[0030] The applicant unit combined production and scientific experiments, through years of continuous search and screening, finally found an organic acid salt substance with a carboxylic acid group that can inhibit iron oxide, which is the α-isomer of sodium glucoheptonate. The experiment uses tin-iron symbiotic oxide ore in the Gejiu tin mine area of ​​Yunnan. The target mineral is cassiterite, the main gangue mineral is hematite, and calcium oxide ore. First, grind and dissociate the mineral raw materials to -300 mesh, use a 1L flotation machine to go through a rough sweep and two sweeps, and use this inhibitor. The rest of the experimental conditions are as follows: the regulator is sulfuric acid, the foaming agent is 730A, the rough selection is 8 minutes, the first sweep is 6 minutes, the second sweep is 5 minutes, the stirring intensity is 1200 rpm, and the order of admi...

Embodiment 4

[0036] Although pyrogallol, as a phenolic inhibitor, can strongly inhibit iron-calcium minerals in the separation of tin and iron, it is expensive and difficult to implement in production. The inventors found out that alpha-type sodium glucoheptonate A300 is used in production as a cheaper medicament than pyrogallol, and the cost is feasible, so for the same batch of materials containing 1.02% and 1.08% tin slime (the same Batch slime) test, and the test comparison of tailings containing 0.57% tin to verify its ability to inhibit iron minerals. The inhibitor is high-viscosity carboxymethyl cellulose and sodium humate, the regulator is sulfuric acid, the foaming agent is 730A, the roughing is 8 minutes, the first sweep is 6 minutes, the second sweep is 5 minutes, and the stirring intensity is 1200 rpm Every minute, the order of dosing is ~ first add sulfuric acid to adjust the pH value to ensure 6-6.5 (between 50 ~ 54mv potential), add ∝ ~ sodium glucoheptonate A300, then add c...

Abstract

The invention provides an application technology of sodium glucoheptonate in tin-iron flotation separation, which is characterized in that the sodium glucoheptonate is used as an inhibitor for tin-iron mineral flotation separation, and the application method specifically comprises the following steps: adding 750g of sodium glucoheptonate into each ton of raw ore in dissociated tin-iron mineral pulp according to the weight of the raw ore to inhibit iron-containing and calcium-containing minerals, and floating a target mineral cassiterite into a foam product by using a collecting agent and a foaming agent, wherein sodium glucoheptonate can be combined with phenol substances for use, and flotation operation comprises one-time roughing and 1-3 times of scavenging. Sodium glucoheptonate is used as an inhibitor, the hydrophilicity of iron-containing and calcium-containing minerals is improved, the flotation property difference with cassiterite is enlarged, the agent is environmentally friendly and non-toxic, self-decomposition in circulating water is achieved, decomposition products are free of pollution, environmentally friendly and safe, the cost is low, and compared with the prior art, the agent is high in adaptability to iron and effective even if the content of Fe in the minerals reaches up to 60%.

Description

technical field [0001] The invention relates to non-ferrous metal mineral flotation separation technology, especially the application of sodium glucoheptonate in the flotation separation of tin-tungsten-tin-iron. Background technique [0002] Iron-tin ore is widely distributed in our country. The cassiterite in this kind of ore has fine particles, which are granular aggregates, and are very finely distributed in quartz bodies, iron minerals, and tourmaline aggregates, which makes it difficult to separate iron and tin. Therefore, magnetic Separation operation, this kind of magnetic separation operation is to separate tin and iron as the main purpose, and then carry out gravity separation on the magnetic separation tailings, and finally obtain qualified products. This is a more commonly used technology at present. The process of magnetic separation plus heavy separation has an ideal separation effect for mineral raw materials with large particle size of cassiterite intercalat...
