Role of citric acid in selective flotation of limonite from

·To achieve the efficient flotation separation of limonite from quartz citric acid was utilized as a depressant for quartz in this paper The solubility of limonite was studied using inductively coupled plasma tests ICP and the effect of Fe3 and citric acid on the separation of limonite from quartz under sodium oleate NaOL system was investigate

Upgrading nickel in laterite ores by flotation ScienceDirect

·Flotation has not been successful to recover nickel from laterite ores because of the fine grain and low grade nickel Nickel laterite deposits are generally divided into limonite oxide nontronite clay and saprolite silicate zones A systematic study was conducted on the ore samples sourced from these three categories to see the effect

Enhanced iron extraction from high phosphorus waste limonite

·Successful iron extraction and dephosphorization from high phosphorus limonite by a process of grinding SMR stage grinding and magnetic separation flotation A flotation concentration with Fe grade of % and P content of % obtained under the optimal conditions

Flotation separation of limonite from quartz with sodium

·The flotation behaviour of limonite quartz and their mixture by using sodium oleate as collector were studied systematically in this paper Single mineral flotation tests showed that the

Enhanced iron extraction from high phosphorus waste limonite

·High phosphorus limonite was unable to be efficiently utilized owing to the difficulty in Fe extraction and dephosphorization The requirement for iron ore is increasing with the rapid development of industry Therefore it is necessary to develop a method for the high utilization of high phosphorus limonite

Flotation separation of limonite from quartz with sodium

·The flotation behaviour of limonite quartz and their mixture by using sodium oleate as collector were studied systematically in this paper Single mineral flotation tests showed that the flotation recovery of limonite was much higher than that of quartz in a broad range of pH However flotation tests for the mixture of limonite and quartz

Role of citric acid in selective flotation of limonite from

To our best knowledge however the flotation of limonite has rarely been investigated Liu et al [12] reported that limonite was separated from quartz through reverse froth flotation using a cationic gemini surfactant EDDA which selectively physically adsorbed onto the quartz surface Yu et al [13] noted that limonite could be selectively

The Flotation Separation of Magnesite and Limonite Using

·Mineral mixture tests showed that when sodium silicate was used as an inhibitor for flotation of magnesite and limonite the collector was preferentially adsorbed on magnesite The measured isoelectric points of magnesite and limonite were and respectively Sodium hexametaphosphate significantly reduced the electromotive potential of

Role of citric acid in selective flotation of limonite from

·The solubility of limonite was studied using inductively coupled plasma tests ICP and the effect of Fe 3 and citric acid on the separation of limonite from quartz under sodium oleate NaOL system was investigated using batch flotation tests
