What is Sodium Cyanide used for?

Sodium Cyanide is commonly used in the mining industry for extracting gold from ores.

How can I optimize the use of chemicals in ore processing?

Optimizing the use of chemicals in ore processing involves several strategies to enhance efficiency and cost-effectiveness:

Are there specific regulations for the use of mining chemicals?

Yes, the use of mining chemicals is subject to various regulations that govern their production, use, storage, and disposal. These regulations are designed to protect human health and the environment. Key regulatory aspects include:

What is a settling agent, and how does it work in mining?

A settling agent, also known as a flocculant, is a chemical used to accelerate the settling of suspended particles in a liquid. In the context of mining, settling agents are crucial for improving the efficiency of ore processing and tailings management.

How do I store Sodium Cyanide safely?

Sodium Cyanide should be stored in a cool, dry place, away from incompatible materials and in accordance with safety guidelines.

Comparison of Sodium Cyanide Leaching and Environmentally Friendly Gold Extractant in a Mine Burundi Nātrija cianīds cyanide gold mine oxidized ore sodium leaching tailings grade rate No. 1picture

The ore sample is an oxidized gold ore collected from a concentrator of a gold mine in Burundi. The gold grade of the raw ore is 0.81 g/t, the grinding fineness is -0.074 mm 90%, the pulp concentration is 40%. Lime is used as the pH adjuster. The leaching concentrations of Sodium cyanide and the environmentally friendly gold extractant are both 0.1%. Leaching is carried out at room temperature for 24 hours. After filtration and washing, the gold grade of the tailings is detected, and the leaching rate is calculated. The comparison of the results of cyanide leaching and environmentally friendly gold extractant leaching is shown in the following table.

Leaching time (h)	Leaching residue Au (g/t)	Leaching rate (%)	Dosage of CaO (g/t)	Pulp pH	Agent consumption (g/t)	Gold leaching agent
