Recently, Guoda Company has made a series of breakthroughs in gold smelting technology, relying on its "Key Technologies for Resource Utilization of Complex Copper-Gold Concentrates" to win 2024 the annual China Gold Association Science and Technology Second Prize, and at the same time, the "Synergistic Processing Technology for Arsenic-Carbon-Difficult-to-Treat Gold Concentrates" has successfully obtained a national invention patent authorization. These two innovative achievements mark a new stage for the company in the research and development of comprehensive utilization technology for complex polymetallic resources, injecting new impetus into the sustainable development of the gold smelting industry.
Guoda Company's independently developed "Key Technologies for Resource Utilization of Complex Copper-Gold Concentrates" uses innovative process combinations and system integration to form a 5 major key technology system adaptable to different ore types, successfully solving the technical bottlenecks of low gold and silver copper recovery rates and difficult sulfur and iron recovery in traditional processes, achieving improved comprehensive resource utilization rate and reduced production costs. The overall technology has reached the advanced level of the industry and has broad promotion and application value for the gold smelting industry and the non-ferrous metal smelting industry.
"Synergistic Processing Technology for Arsenic-Carbon-Difficult-to-Treat Gold Concentrates" uses a unique "low-temperature arsenic removal - high-temperature desulfurization, arsenic removal, carbon removal, and acid leaching - flotation - graded sodium cyanide concentration control" process chain to overcome the technical difficulties of low valuable element recovery rate in carbon-arsenic gold concentrates, improving gold leaching rate and reducing sodium cyanide consumption. This technology not only achieves comprehensive recovery of valuable metals but also builds a closed-loop clean production system, opening up a new environmentally friendly path for the treatment of difficult-to-smelt gold ore resources.

Gold prices rise again! Multiple risks fuel safe-haven demand.
From the perspective of the international market, the tense situation in the Middle East, the escalation of the Russia-Ukraine conflict, and the continued high uncertainty surrounding the US Trump administration's tariff policies have driven up gold prices due to increased risk aversion in the market. Furthermore, a significant recent change in the gold market is that gold has become the second-largest reserve asset for central banks globally. How should the future trend of gold prices be viewed? Several analysts have indicated that in the short term, gold prices may fluctuate due to factors such as tariff easing and sudden changes in the geopolitical situation; in the medium to long term, gold prices are still in an upward channel.
As the Russia-Ukraine conflict enters its third year, global attention is once again focused on this geopolitical crisis. According to Dow Jones Newswires, US President Donald Trump made startling remarks at the White House on Thursday (June 5), stating that neither Russia nor Ukraine is prepared for peace, and that both sides may "continue fighting" until one side is willing to compromise. This statement not only signals the failure of his attempts to broker peace, but also introduces new uncertainty to the global geopolitical and economic markets.
Recently, good news came from the China Machinery Metallurgy and Building Materials Workers' Technical Association. In the 2025 National Machinery Metallurgy and Building Materials Industry Workers' Technological Innovation Achievement Award, Shandong Guoda Gold Co., Ltd.'s "Purification of Crude Arsenic Flue Dust to Produce Arsenic Trioxide Industrial Application" and "Key Technology Application for High-Value Utilization of Complex Copper-Gold Ore Resources" projects won the first prize and the second prize respectively. This honor is a high recognition of the workers' technological innovation ability and the effectiveness of achievement transformation, and also fully demonstrates the company's outstanding strength in the industry.
Gold prices return to $3300! Wall Street banks show significant divergence in long-term outlook
In fact, as gold prices fluctuate, Wall Street's major banks have recently shown a clear divergence in their views on gold prices. Unlike Goldman Sachs and Deutsche Bank, which are optimistic about gold's performance, Citigroup believes that the long-term outlook for gold prices is not optimistic.
Although gold prices rose this week, market volatility has clearly increased. While the US-UK agreement is symbolic, its content is limited and insufficient to alleviate concerns about a global economic slowdown. Therefore, gold prices will continue to fluctuate between safe havens and policy signals, closely monitoring the Federal Reserve's interest rate expectations and global trade sentiment.
