Cyanide Gold Extraction Process

22.May.2026 KZ Editor

Cyanide leaching is the most widely used core process in gold beneficiation. It primarily utilizes the chemical solubility properties of cyanide to efficiently extract gold from gold ore and gold concentrate. This process is complete, technologically mature, and can be extended to the leaching and recovery of metals such as silver, copper, and zinc.

Core Process Technologies for the Upgrading of Phosphate Ore via Flotation

22.May.2026 KZ Editor

The quality and efficiency of low-grade phosphate ore can be enhanced through physical and chemical methods such as crushing and screening, gravity separation, washing, calcination, acid leaching and flotation. Among these, flotation has become the most fundamental and widely applied industrial technology for processing medium- and low-grade phosphate ore, owing to its high enrichment efficiency and broad applicability.

Six Methods for Lithium Extraction from Lithium Ore

21.May.2026 KZ Editor

Due to significant variations in lithium oxide content, mineral composition and mineralisation characteristics among different lithium ores, the extraction process must be selected on a case-by-case basis. Currently, the six mainstream industrial methods for lithium extraction are flotation, magnetic separation, gravity separation, hand sorting, thermal cracking, and combined mineral processing.

Core Process of Iron Ore Beneficiation

15.May.2026 KZ Editor

The iron ore beneficiation process primarily comprises two major systems: crushing and grinding/beneficiation. It employs a combined process of three-stage closed-circuit crushing and staged grinding and beneficiation to achieve efficient ore separation and grade enhancement.

Four Main Methods for the Industrial Purification of Spodumene

15.May.2026 KZ Editor

Industrially, the purification of spodumene primarily employs four mainstream processes: flotation, heavy-medium separation, magnetic separation, and combined beneficiation.

Key Points of the Barite Purification and Whitening Process

14.May.2026 KZ Editor

The whiteness and purity of barite directly determine its application value. Natural barite typically contains coloring impurities such as iron and titanium, as well as gangue minerals such as silicates and carbonates; therefore, it must undergo efficient purification and whitening treatments to meet the requirements.
