Eco-Friendly Sodium Mercaptoacetate Collector for Non-Ferrous Metal Ores

Product Introduction

Sodium Mercaptoacetate, also known as thioglycolic acid sodium salt, is an efficient and low-toxicity organic depressant widely used in the flotation separation of sulfide minerals. It effectively suppresses copper sulfide minerals such as chalcopyrite, and can also inhibit pyrite and galena. Its key application lies in replacing highly toxic reagents like sodium cyanide or sodium sulfide during the separation of copper-molybdenum bulk concentrates.

The compound contains both -SH and -COOfunctional groups. The -SH group enables strong chemical adsorption  onto mineral surfaces, often through chelation or complexation with metal ions, while the -COO⁻ group enhances hydrophilicity. This adsorption makes the targeted mineral surfaces hydrophilic and negatively charged, reducing their floatability. SMA demonstrates high depression efficiency, often at lower dosages compared to traditional depressants, and its low toxicity and biodegradable nature contribute to more environmentally friendly mineral processing operations.

Product Advantage

1.Sodium Mercaptoacetate offers significant advantages in mineral processing as a highly effective and selective organic depressant.  Its primary strength lies in its ability to strongly and selectively inhibit copper sulfide minerals, enabling the critical separation of complex ores like copper-molybdenum concentrates. The molecule's functional groups allow for specific chemical adsorption onto mineral surfaces, rendering them hydrophilic and preventing flotation. This targeted action is often more efficient than traditional depressants, frequently achieving superior esults at lower dosages and helping to reduce overall reagent consumption.

2.A major benefit is its enhanced safety and environmental profile compared to traditional reagents. As a low-toxicity and biodegradable alternative, it provides a safer solution for replacing highly toxic chemicals like sodium cyanide or sodium sulfide in flotation circuits. This shift not only mitigates environmental impact but also improves workplace safety. Combined with its cost-effectiveness in many applications, these properties make Sodium Mercaptoacetate a valuable reagent for achieving selective separation while supporting more sustainable and responsible mineral processing operations.

Technical Parameters

Product Uses

Main Purpose: Sodium Mercaptoacetate is an effective inhibitor for cyanide-free flotation of molybdenite, which can replace sodium cyanide (highly toxic) and sodium sulfide. It can selectively inhibit copper and sulfur associated with molybdenite, especially copper sulfide and pyrite.
