Flotation Rutile 1966

Results are presented which indicate the effect of pH and flotationcollector type upon the flotation rates of natural rutile particles. Above pH 2.5 flotation rate decreases with increasing pH for anionic collectors and increases with increasing pH for a cationic collector.

Rutile is recovered from copper ore tailings by means of a froth flotation process comprising a flotation of sulfides and carbonates at a pH of about 9 to 10 using sodium isopropyl xanthate and sodium oleate as collectors and detrine as rutile depressant and b flotation of rutile from the resulting tailings at a pH of about 2 to 3 using hydrofluoric acid as a rutile selectivity

Flotation recovery of rutile decreases sharply with the increase of pH and remains constant after reaching approximately 3 at a pH of 5.3 which means the flotation of rutile is almost inhibited. The flotation recovery of rutile as a function of lead ions and aluminium ions concentration in the

The flotation behavior of rutile in the system with sodium oleate as collector was studied through pure mineral test. When the dosage of sodium oleate is 20 mgL and pH value of the pulp is set

A Century of Developments in the Chemistry of Flotation Processing Douglas W. Fuerstenau Dept. of Materials Science and Engineering 1966 showed the change in the eta potential of rutile depending on double bonds in the alkyl chain with the

Therefore a NaOl concentration of 1200 gt was selected as the experimental dosage consumption and used in subsequent experiments. In order to investigate the effect of the pH value on the rutile flotation when the NaOl dosage was 1200 gt micro

Potential byproduct rutile resource in the active western copper mines to be in excess of 5 million mt with a potential rutile recovery rate of 300 mtd. Sullivan and Llewellyn estimated that recovery of rutile from two of the tail173 ings they investigated would amount to about 32 pct of 1980 U.S. imports. A rutile flotation technique for

Rutile flotation without grinding the plus 200mesh material is feasible and appears to be the most promising technique for rutile beneficiation. A rutile concentrate grading 34.7 percent TiO2 with recoveries of 69.4 percent of the recoverable TiO2 and 36.8 percent of the total TiO2 was obtained using as

The second peak was at about pH 2.53.3 which is similar to the flotation behavior of rutile Bulatovic and Wyslouil 1999. The flotation recoveries for ILF ILQ and IL

They said the reserve doubled the worlds known reserves of rutile and that their project would end a worldwide shortage of the mineral by late 1966. Rutile is the essential raw material in the

The Bureau of Mines investigated the potential for recovering rutile and associated valuable heavy minerals from the Central Florida Pebble Phosphate District flotation circuits. Studies were made to determine 1 the type and quantity of valuable heavy minerals present at various points in the flotation circuits and 2 the technical

It is of great significance to study the adsorption mechanism of collectors at the rutilewater interface for the development and utiliation of rutile 8915.Only when the adsorption mechanism of the collector on the mineral surface is clear enough can a flotation collector with low toxicity and high efficiency be designed by changing the functional group and carbon chain length.

Since 1948 flotation commercially has been used to provide monaite concentrates 9. Due to the very similar surface properties of monaite and associated minerals mainly ircon and rutile 203234 upgrading by means of selective flotation requires the utiliation of adequate combinations of collectors and depressants 35. 2.

Flotation ceases above p H 12.2 because of hydrolysis of the collector to the amine molecule. Flotation falls off for two reasons The concentration of R N H 3 is diminished as the p H is increased and at the same time there is 6 PRINCIPLES OF MINERAL FLOTATION 113 ionic competition from the increasing N a concentration.

On the basis of these previous studies we found that the activation mechanisms of metal ions for mineral flotation were indirectly deduced by some measures such as XPS eta potential FTIR and simulation calculation 568910111213.However at the micro level there was no intuitive evidence for the explanation of the activation mechanisms of Pb 2 ions for rutile flotation.

The recovery of such strategic minerals from the above untapped and unconventional resources however will not be easy and will have a major impact on mineral processing developments. It will be necessary to develop new processes and techniques based on physical chemical or even biological characteristics of the minerals involved.
