Definitions
- the invention relates to a process for the extraction of minerals from non-sulfidic ores by flotation, in which esters of dicarboxylic acids with fatty acid monoalkanolamides, optionally in a mixture with other anionic or nonionic surfactants, are used as collectors.
- Flotation is a generally used sorting process for separating valuable minerals from the gangue, which is used to prepare mineral ores.
- the ore is first ground and dry, but preferably wet, and suspended in water.
- a collector is added, often in conjunction with other reagents, which include foaming agents, regulators, pushers (deactivators) and / or Beieber (activators), to separate the valuable minerals from the gangue minerals in the ore during the subsequent flotation supports.
- these reagents are usually allowed to act on the finely ground ore for a certain time (conditioning).
- the collector causes the surface of the minerals to become hydrophobic, so that these minerals adhere to the gas bubbles formed during the aeration.
- the mineral components are made hydrophobic selectively in such a way that the undesirable ones Components of the ore do not adhere to the gas bubbles and remain behind, while the mineral-containing foam is stripped off and further processed.
- the aim of flotation is to extract the mineral of value from the ores in the highest possible yield and at the same time to obtain the best possible enrichment of the mineral.
- collectors In the flotative processing of non-sulfidic ores, mainly anionic or cationic surfactants are used as collectors. These have the task of adsorbing as selectively as possible on the surface of the valuable minerals in order to ensure a high concentration in the flotation concentrate. In addition, the collectors should develop a stable, but not too stable, flotation foam.
- collectors frequently used in the flotation of non-sulfidic ores, such as. B. fatty acids or alkyl sulfosuccinates [ Aufberei ⁇ tionstechnik, 26, 632 (1985)], but in many cases do not lead to a satisfactory yield of valuable minerals with economically justifiable collector quantities.

- the invention relates to a process for the extraction of minerals from non-sulfidic ores by flotation, in which ground ore is mixed with water to form a suspension, air is introduced into the suspension in the presence of a collector system and the resulting foam together with the foam contained therein separates flotated solids, and furthermore as a collector ester of Dicarboxylic acids with fatty acid monoalkanolamides are used which follow one of the formulas (I) to (VI),

- collector AI maleic acid oleic acid monoethanola idester
- the flotation task had the following grain size distribution:
- the collectors according to the invention were used alone and in combination with an alkyl sulfosuccinate Na / NH4 salt (B1) or a technical oleic acid (B2) as co-collectors, the mixing ratio collector: co-collectors 50:50 to 70:30 Parts by weight was.
- a Denver laboratory flotation machine type D1 was floated in the 2-1 cell, the cleaning stages (2 to 4 Post-cleanings) were carried out in a corresponding 1-1 cell.
- Water of 3 ° d was used as the flotation water; the cloud density during pre-flotation was approx. 500 g / 1.
- a phenol-formaldehyde condensate (Cl) was used in a dosage of 200 g / t.
- the pH of the slurry was adjusted to 10 with sodium hydroxide.
- the conditioning of the reagents was carried out with stirring at a stirrer speed of 1000 rpm, the conditioning time for pushers and collectors was 5 minutes in each case.
- the flotation was carried out at a speed of 1100 rpm (2-1 cell) or 1000 rpm (1-1 cell), the flotation time was approximately 4 minutes, during which the flotation foam was removed manually.
- Example 1 In the cleaning flotations, the flotation concentrate of the pre-flotation (rougher concentrate) was added to the 1-1 cell without the addition of reagents and flotated at 1000 rpm for about 4 minutes.
- Example 1 and Comparative Example 1 were each carried out with 4 cleaning stages, and Examples 2 to 5 with two cleaning stages. The results obtained are summarized in Tab. 1.
- Examples 1 to 5 show that when the esters are used as collectors in the sense of the invention, a higher P 2 ⁇ 5 output can be achieved with the same dosage than using the standard collector oleic acid.
- the esters are combined with standard collectors, an increase in the selectivity towards the valuable minerals is observed, so that fewer cleaning stages are required to achieve salable mineral concentrates.
- Tab. 1 Flotation of minor apatite ore in the Denver cell; Percentages by weight
- the ore was already ground up in the slurry. After wet sieving, a particle size fraction of 50-100 ⁇ m was used as the task. A modified Hallimond tube with a volume of 165 ml and a stirring speed of 400 rpm was used as the flotation cell. In each case, 2 g of ore (dry content) were conditioned and floated at pH 10 (adjusted with sodium hydroxide) in water at 20 ° d (calcium ions only). The conditioning time for the hardening water was 5 minutes, for the collector 10 minutes; the flotation was carried out over a period of 2 minutes.
- the collectors according to the invention were used alone or in a mixture with co-collectors.
- the alkyl sulfosuccinate (B1, comparative test V2) was used as the reference substance.
- the results of the flotation tests are summarized in Table 2.
- Examples 6 to 8 show that the use of the esters of dicarboxylic acids with fatty acid monoalkanol amides - alone or in mixtures with standard collectors - as collectors in the sense of the invention improve both the phosphate content in the concentrate and the mass and thus also the phosphate yield.
