Introduction: The overlooked "alchemist" often attracts everyone's attention in the magnificent mining scene, with giant mechanical equipment - hundred meter deep mines, roaring crushers, and huge flotation tanks forming people's intuitive impression of gold mining ..

Introduction: A historic decision for an industry. The gold mining industry is standing at the most important crossroads of a century. The cyanide gold extraction process, which has been used for over a hundred years, has created enormous wealth but also left indelible environmental scars and community pain. ...

Introduction: Why is "correct choice" more important than "advanced technology"? In today's industry where environmentally friendly mineral selection agents have become a consensus, facing the complex situation of dozens of technical routes and hundreds of suppliers in the market, which environmentally friendly agent to choose ..

Introduction: The inevitable choice at the crossroads of mining. Modern mining is standing at a historic crossroads: one end is the traditional extraction process that has lasted for a hundred years, and the other end is the green future led by carbon neutrality and sustainable development. The rise of environmentally friendly gold extractants is driving mining ..

When you see dazzling gold jewelry or standard gold bars, it may be hard to imagine that they were originally just tiny particles hidden in tons of rock. Extracting gold from hard minerals is a precise system engineering that combines physical strength and chemical intelligence ..

Introduction: When scale encounters challenges in the era of large-scale mines, the super beneficiation system that processes millions or even tens of thousands of tons of ore per year imposes stricter requirements on beneficiation agents than conventional ones. This is not just simple; Quantity "; Let it go ..

Introduction: When gold meets the trend of green chemistry in the era of sustainable development and ecological civilization construction, the gold mining industry is facing unprecedented transformation pressure. The environmental hazards of traditional cyanide processes are like Damocles hanging over the industry ..

Introduction: As green becomes the new normal for mining, in the grand narrative of global carbon neutrality and sustainable development, mining is undergoing a profound green transformation. This transformation is not only reflected in the electrification of large equipment, but also embedded in every process ..

Introduction: A revolutionary solution to address the global challenge of low-grade resources. With the increasing depletion of high-grade gold resources worldwide, how to economically and efficiently develop millions of low-grade oxidized gold resources has become the core challenge of the industry. Heap leaching ..

In the field of gold beneficiation, mining specific gold extractants, as tailored "efficient keys" for specific ores, have value not only in advanced formulas themselves, but also in every management link from factory to use. Scientific and standardized preservation and management ..

In the complex chain of gold mining, the gold extraction process is the crucial step that determines economic benefits. Universal gold extractants (such as traditional sodium cyanide) are like "broad-spectrum antibiotics", although they have certain effects, they often face vastly different mineral "constitutions" ..

In the long process of human development and utilization of mineral resources, gold mining has always occupied a special position. However, the highly toxic environmental risks associated with traditional cyanide gold extraction processes, like the sword of Damocles, hang high above the sustainable development of mines. Low toxicity ..

Gold leaching is a key metallurgical step in extracting gold from ores, and the choice of leaching agent directly determines the extraction efficiency, economic cost, and environmental impact. This article systematically elaborates on the core definition, mechanism of action, main types, and technologies of efficient gold leaching agents ..

In the field of gold mining, the pursuit of efficient, safe, and environmentally friendly gold extraction technology has never stopped. The traditional cyanide method is facing increasingly severe challenges in terms of environmental safety and social responsibility due to its high toxicity. In this context, low toxicity and environmentally friendly gold selection agents are considered as ..

In the grand narrative of gold mining, the crushing, grinding, and flotation of ores form a spectacular physical prologue, and the true core of alchemy is often hidden in colorless or slightly turbid chemical solutions - gold extractants. They may not show any signs of mountain dew ..

1、 The core function of traditional mainstream agents (represented by sodium cyanide) is that sodium cyanide is currently the most widely used gold extraction agent worldwide, and its mechanism of action is very classic: dissolution (core chemical reaction): under alkaline and aerobic conditions, cyanide ions are extracted ..

In the global wave of sustainable development in mining, environmental protection is no longer a multiple-choice question, but a necessary answer that concerns the future and social responsibility of enterprises. The traditional gold beneficiation process often involves the use of highly toxic substances such as cyanide, which poses potential risks to the ecological environment ..

The core goal of environmentally friendly gold beneficiation agents is to safely and efficiently extract gold from ores without relying on or significantly reducing highly toxic cyanides. The principle depends on the specific type of agent, such as thiourea, thiosulfate, halide, polysulfide

1. The product is non flammable, non explosive, non hazardous to oxidants, non radioactive, and has no other transportation hazards. It can be transported by road, railway, sea, and air. 2. The product is prone to moisture absorption and should be moisture-proof, moisture-proof, waterproof, and sealed. It should be placed in a cool and dry place and sealed ..

（1） Soak test (suitable for gold oxide ore, semi oxidized primary ore, cyanide residue, silver ore) 1: Take 500g-1kg of comprehensive ore sample, and the ore with poor oxidation degree must be crushed to about 5mm and placed in an open (basin) container for later use. 2...
