Carboxymethylcellulose (CMC) is a nontoxic and biodegradable polysaccharide, which can
potentially replace the frequently used hazardous depressants in Cu–Mo separation …

The dewatering of tailings is one of the serious challenges that the mining and mineral
processing industries have encountered internationally. Solid–liquid separation methods …

Abstract Development of cationic flocculants from lignocellulosic wastes not only eliminates
the health and environmental concerns associated with the use of conventional chemicals …

Here we report on solution properties and flocculation performance of polyampholyte
chitosan derivatives–N-carboxyethylated chitosans (CEC)–synthesized “in gel” by treatment …

In the papermaking process, the removal and control of dissolved and colloidal substances
(DCS) is a key issue for reducing the usage of fresh water. Nano-size TiO2 is an excellent …

In this study, tamarind polysaccharide gum was first used in the sulfidization flotation of
azurite to improve the Cu grade of the concentrate via the depression of talc. The flotation …

The flocculant made from natural polymers gained prominence in recent years due to its eco-
friendliness and low cost. In this study, two natural polymers of chitosan and fulvic acid were …

Herein, we report a novel renewable pH-responsive starch-based flocculant (CIAT-ST) via
etherifying 2-chloro-4, 6-isopropylamino-[1, 3, 5]-triazine (CIAT) onto the starch backbones …

The present paper aims to use natural biodegradable polymers of chitosan (CS) and
cellulose (CEL) to synthesize green chitosan-cellulose (CS-CEL) nanocomposite as a new …

ABSTRACT A new flocculant was synthesized through the modification of sodium alginate
with thiosemicarbazide. In the preparation, amino thiourea groups which had excellent …
