Mechanisms of Dodecylamine Flotation of

Primary monoamines have been long used and studied as flotation collectors for quartz. In the past several mechanisms have been proposed to explain the manner in which the amines adsorb onto and render the mineral hydrophobic and, thus, floatable.Diamine flotation of quartz - ScienceDirect,Diamine flotation of quartz 149 Comparison of Figures 1 and 3 with Figures 5, 6, 7 and 8 illustrates the importance of the doubly charged species in promoting flotation.Mechanisms of Dodecylamine Flotation of Quartz,The flotation of quartz and magnetite was studied as a function of pH when using N-alkyl-1, 3 diaminopropanes and n-dodecylamine as collectors. The alkyl chains of the diamines were 8, 12 and 16 carbons in length. Two collector concentrations were used and flotation studied in the absence of additives and in the presence of NaCl.

Flotation separation of cervantite from quartz

cervantite from quartz by flotation is challenging. Dodecylamine (DDA) is an effective collector for oxide ores and is widely used in flotation of zinc oxides, bauxite, collophane and rejection of silicates from iron ores through reverse flotation (Majid et al., 2011; Filippov et al., 2014; Liu et al., 2015a, 2015b).of Quartz by - Columbia University,Dodecylamine Flotation of quartz at pH 6.5*0.5 is given in Figure 1 as a function of dodecylarnine hydrochloride concent~ion.

Developing Effective Separation of Feldspar and

The micro-flotation tests revealed that there was little difference in the flotation of feldspar and quartz at pH 2, using H 2 SO 4 as pH regulator. After HF pretreatment, the floatability of feldspar significantly increased while the floatability of quartz showed no change.Froth Flotation – Non Sulphides [Experiment 3] |,28.09.2011· Micro-flotation cell 50 g of -250 + 100 µm quartz per Test (Ore is to be ground prior to using it in tests) Sodium oleate – 0.1M Dodecylamine chloride – 0.1 M Sodium hydroxide – 0.01M Hydrochloric acid – 0.01M Calcium chloride – 0.01M Frother – MIBC.

A new collector used for flotation of oxide minerals

that ND has stronger capability to quartz than dodecylamine, while the flotation recovery of hematite with ND as collector is poorer than that with dodecylamine. So, ND can be used as collector in the reverse flotation of hematite by adding proper depressor such as amylum.
