Problems solved by technology

[0006](2) It is easy to bring the non-purpose minerals in the ore into the flotation concentrate, resulting in a decline in the quality of the concentrate product
[0007] (3) The pH value of the pulp has a great influence on its capture performance
[0009](5) The recovery rate of concentrate is relatively low, generally 50-60%
[0010](6) There are more flotation foams, which is prone to "running the trough", making it difficult to defoam the concentrate and increase the difficulty of filtration and dehydration, making it difficult to operate , it is difficult to be practically used

Embodiment 1

[0032]Embodiment 1: Flotation of a magnesium-manganese type siderite in Anning, Yunnan Province {divided into low-copper and low-sulfur magnesium-manganese (Cu≤0.1%, S≤0.1%) and high-copper high-sulfur (Cu≥0.2%, S≥1.96 %) two kinds of magnesium manganese siderite},

[0033] The ratio of raw materials is: S preparation ratio S 1 = 30 S 2 =30P 2 =40; P preparation ratio S 3 =20S 4 =30P 1 =10P 3 = 40; SP preparation ratio S = 60 P = 40, according to the above method to prepare the SP collector. The collector is used to replace the existing chemical system, and the test results are shown in Tables 1-2.

Abstract

The invention relates to a siderite flotation collecting agent and a preparation method thereof. The collecting agent takes lauryl amine, mixed amine, polyether amine, naphthenic acid, sulphuric acid, hydrochloric acid and caustic soda as raw materials and after adding accessory materials to prepare a complex collecting agent. Adopting the collecting agent for siderite flotation and collection not only raises the grade of siderite ore concentrate but also raises the coefficient of iron recovery over 80 percent. The invention also has good performance in collecting complicated and polymetallic ore mineral which mainly contains siderite. The siderite flotation collecting agent preparation method has the advantages of good selectivity, little interference by other ions in ore slurry, strong collecting property, thus realizing the effective separation of siderite form other ores during flotation; the collecting agent has certain foaming tendency, which can reduce the usage of 2oil which is often used in flotation technique, can reduce ore choosing cost, thereby raising the economic benefit correspondingly.

Description

1. Technical field [0001] The invention relates to a preparation method of a reagent for mineral processing in the field of mineral processing engineering, in particular to a high-efficiency collector for flotation siderite and a preparation method thereof. 2. Background technology [0002] At present, there are relatively few types of collectors for siderite, and the flotation of siderite has always used oxide ore type collectors for flotation. Iron ore collectors are generally divided into two categories: anion collectors and cationic collectors. There are many types of iron ore anion collectors, which can be divided into the following types according to the composition and structure of the solid group: carboxylic acid And its soap-RCOOH (Na, K), also known as fatty acid (soap), the most commonly used are oleic acid and its soap sodium oleate; hydrocarbyl sulfonate-RSOH (Na, K), such as sodium petroleum sulfonate, is It is obtained after sulfonation and saponification of ...
