Adsorption mechanism of lead ions at ilmenite/water

The adsorption mechanism of lead ions at water/ilmenite interface and its influence on ilmenite flotability were evaluated in present paper through zeta potential analysis, adsorption density calculation, FTIR and XPS analysis. The results showed that the addition of lead ions could make zeta potential of ilmenite shifted positively, which was beneficial to the interaction between negatively charged oleate

Influence of Fe2+ ions of ilmenite on its flotability

Influence of agitation time on the flotability of ilmenite in distilled water containing oxygen. RESULTS The oxidation of Fe2 + ions An Erlenmeyer flask with 0.5 g of ilmenite sample and distilled water, in which the oxygen concentration is 6.8 mg 1 1, was vibrated for a specific period of time on a vibrator. Then the sample was poured, filtered and floated in a Hallimond tube. Fig. 1 shows that if the

Effect of Copper and Iron Ions on the Sulphidizing

The treatment of smelting slag has attracted much attention nowadays. This study investigates the influence of Na 2 S, CuSO 4 , and FeCl 3 on sulphidizing flotation of copper oxide. The results show that a proper Cu 2+ concentration can increase the sulphidizing effect of copper oxide, while Fe 3amp;x2b;lt;/supgt; inhibits the sulphidizing effect.

Gravity separation, magnetic separation, and flotation are often combined to the separation of ilmenite and rutile from gangues [ 5 ]. For ilmenite, there are many pretreatment methods to improve its flotability, such as the surface dissolution method, oxidation roasting, microwave irradiation, and

2. Occurrence of oxidized Cu minerals in copper ores converted in KGHM More than 120 oxidized copper minerals are known, but as practice indicates, commercial meaning is primarily malachite and azurite, to a lesser extent cuprite, tenorite and chrysocolla. The most important properties of selected oxide copper minerals are given in table 1. Table 1.

Flotability of laurionite and its response to

The microflotation experiments results indicated that Na 2 S would improve the flotability of laurionite within a moderate dosage, otherwise decrease its float. The negativity of zeta potential observably increased when adding an appreciate amount of Na 2 S prior to NaBX, indicating a better adsorption of BX on mineral surface, which would increase the flotation recovery.

Surface oxidation is one of the most imponant factors that influence the flotation selectivity and recovery in the processing of complex sulphide ores. It is an inherent part of surface chemical reactions that determine whether the surface fJ.1m formed on a sulphide mineral will

The effect of Pb(NO3)2 on ilmenite flotation ScienceDirect

Ilmenite represented the dominant opaque oxide mineral in the form of granular aggregates or clusters of grains. Hematite and ilmenite formed a complete solid solution series. Magnetite was commonly present as components of granular ilmenite aggregates. The main gangue minerals were silicates such as quartz and feldspar. Small amounts of olivine, brown mica and sulphides were also observed in
