Smelting Industry

The company has been positioned as a professional gold smelting enterprise since the beginning of its establishment. After 17 years (2008-2024) of research and development, the company has successfully established a cyanin-free fire process and environmental protection metallurgy technology system, which has promoted the intergenerational innovation of gold smelting technology and is the leader and source of the transformation and upgrading of gold smelting industry.

After years of development, gold smelting technology has undergone five changes
  • Gravity separation method and amalgamation method
    First Generation
    Gravity separation method and amalgamation method
  • Direct cyanide method
    Second Generation
    Direct cyanide method
  • One-stage roasting cyanide gold extraction
    The Third Generation
    One-stage roasting cyanide gold extraction
  • Pre-oxidization-cyaniding method
    The Fourth Generation
    Pre-oxidization-cyaniding method
  • Cyanide-free pyrometallurgical processss
    The Fifth Generation
    Cyanide-free pyrometallurgical processss
Create a new path of cyanide-free pyrometallurgy

The first four generations all belong to the traditional hydrometallurgical process, which has the advantages of less capital occupation and short metal realization cycle, but also has problems such as hazardous cyanide slag waste, high ore quality requirements, low metal recovery rate and difficult extraction of associated elements, resulting in the waste of mineral resources. The fifth generation of cyanide-free pyrometallurgical technology system developed by the company has cured hazardous cyanide slag from the source, and has strong raw material adaptability, as well as significant advantages of multi-element extraction, low comprehensive energy consumption and high metal yield. Based on this, the company has won 2 second prizes of National Science and Technology Progress, 10 first prizes of provincial and ministerial science and technology progress, national green factory, national energy efficiency "leader" and many other honors.

Realize high value utilization of all elements

Based on the advantages of cyanide-free fire technology, with the mission of "developing limited resources and infinite value · leading the green development of gold mining and metallurgy", the company has firmly established the development concept of "full productization of valuable elements, green, low-carbon and zero waste", and opened up a diversified industrial path of "full element recovery and high purification manufacturing" on the basis of "cyanide-free metallurgy". To this end, since 2008, the company has successively built 4 sets of cyanide-free pyrometallurgy production systems, 1 set of refining production system, 1 set of high-purity material research and development and preparation system, with an annual capacity of about 2.15 million tons of complex raw materials, and 1 1.4 million tons of cyanide-free pyrometallurgy production system under construction. The annual output of the existing system is approximately 96 tons of gold, 1,000 tons of silver, 250,000 tons of electrolytic copper, 100,000 tons of lead ingots, 15,000 tons of zinc ingots, 1.3 million tons of sulfuric acid and 30,000 tons of various small metals. In addition, in terms of high-purity materials, the company has conquered 26 products in seven series, making the company become a well-known supplier of high-end metal materials in the world, and also become an active participant in the "national tool" and "intelligent manufacturing of a big country".

Facing the future, with the belief pursuit of"Shandong Humon Smelting Co., ltd. height is the world height, Shandong Humon Smelting Co., ltd. purity is the world purity",Shandong Humon Smelting Co., ltd. shares will portray the picture of "endless innovation, breaking through no limit" more gorgeous.
Copper smelting system innovation, developed a new green cyanide-free and efficient utilization process of "melting gold capture - directional arsenic removal - efficient arsenic collection - arsenic resource recovery" for high-arsenic complex gold concentrate, and established the world's first set of annual demonstration production line for processing 600,000 tons of high-arsenic complex gold concentrate. The recovery rate of gold increased by 5%-13%, the recovery rate of silver increased by 8%-18%, and the recovery rate of arsenic reached 95%. The breakthrough of this technology has solved the problem of large amount of cyanide slag from the source, realized the efficient utilization of resources and the green reform of gold extraction technology, and promoted the iteration and upgrading of China's gold smelting technology.
Lead smelting innovation, the first "bottom blow smelting - melting reduction - oxygen rich volatilization" three furnace continuous lead smelting technology. It broke through the technical bottleneck of the matching of material flow and energy flow in the continuous lead smelting process, realized clean, efficient and continuous production, and effectively solved the environmental, energy consumption and safety problems caused by the discontinuity of the lead smelting process. The total lead recovery rate was more than 98.5%, and the comprehensive energy consumption of crude lead was reduced to below 180kgce/t.
The refining system was innovative, and the new cascade recovery process of "multi-stage oxygen pressure alkali leaching combined with acid roaching to collect arsenic-antimony phase sulfurization sodium activation deep reduction to extract antimony - vacuum distillation to extract lead and bismuth-iron salt induced slag-making to decopper and efficient to extract gold and silver" was pioneered, and the world's first demonstration production line for the coordinated disposal of secondary antimony materials with an annual treatment of 18,000 tons of anode mud was established. The innovation of the production technology of highly scarce strategic metal antimony has overcome the world's technical problems and led the international technological progress of efficient utilization of complex antimony resources.
