    A process for the separation of phosphate minerals from a phosphate-carbonate ore, by flotation, wherein a phenol polymer such as a resol or a novolak, which improves the yield and selectivity of the phosphate minerals with respect to the carbonate minerals, is used in addition to a collector agent in the flotation.

    专利说明:

    The invention relates to the enrichment of minerals, in particular, methods for separating phosphate minerals from phosphate-carbonate ore by flotation.
    The purpose of the invention is to increase the selectivity of flotation and extraction of phosphate minerals.
    The method includes the introduction of pulp containing phosphate-carbonate ore, a modifier of resole or novolak modified with melamine, processing of the pulp with a fatty acid type collector, blowing agent and flotation of phosphate minerals.
    Resole or melamine-modified novolac are synthetic polymers. In the literature it is noted that the resol can be prepared from phenol and formaldehyde, for example, in the presence of an alkaline catalyst. The addition reaction of phenol and formaldehyde with an alkaline catalyst proceeds faster than the subsequent condensation reaction. It follows that saligenins are the predominant intermediate products. The reaction equation has the following form:

    Saligepins containing reactive methylol groups are further condensed with another methylol group, forming ether bonds, or (more often) with reactive atoms of the benzene ring (in ortho or paradosostia), forming methylene bridges like in novolaks. In both cases, water is released in the reaction.
    Resols may, for example, contain on average three to four benzene rings. For example, the following equation:
    ONON
    CH2 x CHrO-CH2xi, CH2OH

    Resols include, in addition to water, phenol residues, saligenins, and formaldehyde polymers.
    The use of phenol polymers during flotation improves the selectivity, purity, extraction, and quality of the foam. The use of phenol polymers provides an efficient use of non-selective collectors such as fatty acids, amino acids, sulfonic acids, and mixtures thereof. In flotation, conventional adjustment agents known in the art can be used, such as: emulants, emulsifiers, dispersants, and foaming oil. During the flotation process, the usual physical conditions such as temperature and the concentration of hydrogen ions of the suspension are regulated in a known manner.
    Pr im. Phosphate-carbonate ore, which included 9.6% of fluorapatite, 30.8% of carbonates and the remainder in the form of silicate minerals, was crushed to a grain size below

    3 mm. Take 1 kg of homogenized ore, add 0.7 l of water and grind to a grain size of 37% - 74 mm. The ground material was weighed in 3 liters of water. Resol was added to the suspension (125 g per 1 ton), tall oil fatty acid (50 g per 1 ton) and triethoxybutaine (10 g per 1 ton). The suspension was stirred for 10 minutes. Then a rough flotation was carried out in a vessel with the capacity of Zl. The preliminary concentrate obtained was subjected to thin flotation three times in a 1.5 liter vessel, and the following results were obtained:
    % Recovery
    Ore4.0
    Apatite concentrate 35.9 80.6
    The table below shows the results of flotation of phosphate-carbonate ore using the claimed and known modifiers.
    Thus, the use of resole and novolac modified with melamine makes it possible to increase the selectivity of the process (the P20 content in the concentrate is increased to 35.9 39.2%) and the recovery to the concentrate (to 82.3-84.9%).
