Now, the surface charge.collector colloid adsorption hypothesis has been extended to successfully explain the flotation behavior of certain alkali oxyanions including nitrates and sulfates as well as double salts including ite (K 2 SO 4 ·MgSO 4 ·6H 2 O) and kainite (KCl·MgSO 4 ·3H 2 O). As was done previously for the alkali halides ...

Kainite, KMg(SO 4)Cl⋅2.75H 2 O, is one of the most common hydrated sulfate minerals, and it plays an important role as a source of potassium. However, its properties and structure have, to date, been insufficiently studied. In our present work, kainite was investigated using multiple techniques, including single-crystal and powder X-ray diffraction, …

ite is a kind of intermediate material to produce potassium sulfate.And it is also a kind of good compound fertilizer without chlorine.In the experiment,ite was prepared by K-Mg mixing salt from dongtaijinaier salt lake with reverse flotation method to remove sodium and conversion method by adding water.The process conditions such as …

A flotation study was performed for the soluble salts KNO3 and NH4C1 using oleic acid as the collector agent and various pH modifiers. Flotation was performed in one- and two-stage processes. The results of this study show that, as a collector agent, oleic acid enables flotation of NH4Cl and thus makes separation of these soluble salts possible.

The same approach can be use to explain the flotation response of the potassium double salts; ite, kainite, and carnallite.In addition, the sign of the surface charge of ite ...
