CNFREE gold leaching reagent is an eco-friendly gold leaching reagent that can replace cyanide totally in the gold leaching process without changing its original process and equipment. It can be used in gold heap leaching sites, tank leaching sites, CIP or CIL plants, and so on.

But why we should choose CNFREE gold leaching reagent instead of cyanide or other leaching reagents?

1. CNFREE is Better for Environmental Protection

As is well known, cyanide is a kind of highly toxic hazardous chemical, so any misoperation in transportation, storage, use, and other links will cause the events of serious environmental pollution, malignant poisoning, etc.

Therefore, many countries and regions have legislated against or restricted the use of sodium cyanide to extract gold and strictly implemented relevant environmental protection regulations. Numerous environmental agencies, government agencies at all levels, gold mining companies, and people around the mines are trying to find an environmental gold dressing reagent that can replace cyanide in gold production.

2. CNFREE Has Better Results Compared to Cyanide

In order to investigate the difference between NaCN leaching reagent and CNFREE leaching reagent in the leaching effect on gold ore, we choose 3 kinds of gold ore samples to test. With the same cyanide leaching conditions, the research focused on the difference of the leaching agent dosage, leaching rate, gold adsorption rate when using NaCN or CNFREE as the leaching reagent, and also carried out the economic benefit analysis of the comparable projects.

The leaching rate of CNLITE leaching reagent is nearly the same as sodium cyanide leaching reagent, while the cost of leaching is lower. Besides, CNLITE leaching reagent is eco-friendly and low-poisonous, while the sodium cyanide leaching reagent is bad for the environment. The greater thing is, when using CNLITE leaching reagent, you don’t have to change the original process and equipment, which would not cause any additional cost.

CNFREE and Cyanide Comparation

3. CNFREE Has 10 Advantages

High-tech products: It is the world’s first high-tech product to replace sodium cyanide for gold beneficiation.

Low toxicity and environmental protection: the product is non-combustible, non-explosive, non-oxidant risk, non-radioactive, low-toxic, belongs to the ordinary chemical products with environmentally safe.

Stable performance: it can reduce the interference of harmful substances such as arsenic and sulfur.

Strong applicability: it is suitable for heap leaching, pool leaching, and the CIP process of oxidized gold and silver ore. The scale can be large or small, and it is more suitable for large-scale heap leaching.

High leaching rate: it can leach the gold ions effectively and can achieve faster with a higher recovery rate than using sodium cyanide.

Faster recycling: compared with using sodium cyanide, the heaping process is shorter and the recovery is faster.

Lower cost: it can reduce costs such as purchasing, transportation, warehousing, storage, usage, safety, and environmental protection facilities.

Selective adsorption: activated carbon has the ability to selectively adsorb gold in gold and copper in gold leaching solution, which is beneficial to the separation of copper and gold.

Easy to use: the production process is consistent with the condition of using sodium cyanide, which makes it easy to use and promote.

Easy to transport: it is an ordinary cargo and can be transported by air, sea, road, or rail.

4. CNFREE Has Free Samples to Test

For gold leaching plant owners or mining reagent traders who never used CNFREE gold leaching reagent or such cyanide substitute before, we can provide free samples for you to test the effect of CNFREE gold leaching reagent, and see if it suits you best. Besides, our technicians would give you the best guidance to know how many bags you need to buy and how to use them for the best results.
