Cost-effective gravity separator machine series for mining

According to the Mining.com website, Guinea's Ministry of Mines has once again completely suspended all development activities at the Simandou iron ore project because the two related companies failed to reach an agreement on the establishment of a joint venture within an extended period.Guinea's mining minister, Moussa Magassouba, who is also a member of the current military government, said that neither Rio Tinto's subsidiary Simfer nor the Win Alliance lacked the will to cooperate, and the local media dreamed of Guinea (Vision Guineae) reported that."The timing of the company's implementation of the framework agreement was too far behind our expectations. This situation is no longer a pity but totally unacceptable," Magasoba said.The minister added that although "the Guinean government has made significant concessions, it is clear that resistance has come from the two companies and the interests of the project have been compromised".Guinea's current government, which came to power in a military coup last September, is growing impatient with the companies that control the giant Simandou deposit.Previously, the Guinean government had ordered the suspension of the construction of the Simandou iron ore mine and supporting infrastructure. In March, Rio Tinto and Win Alliance were forced to sign a framework agreement to "jointly build" the project's infrastructure, including a 670-kilometer railway and a port.In June, the military government gave the two companies another 14 days to discuss the establishment of a joint venture.Guinean authorities say the companies risk losing their licenses if they fail to meet the project's tight deadlines.The mine has not been developed since Rio Tinto obtained an exploration license for the Simandou iron ore mine 25 years ago.The Simandou iron ore is one of the easiest iron ore deposits to develop outside of Australia and Brazil. Its reserves are about 2 billion tons and the grade is as high as 66%-68%.If it reaches full production capacity, Simandou iron ore can export 100 million tons of iron ore annually, making it the fifth largest iron ore in the world.While exporting iron ore through neighboring Liberia is closer and cheaper, the Guinean government has repeatedly demanded that Simandou iron ore developers must build a railroad across the country.

Mkango Resources, which focuses on the exploration and development of rare earth minerals in Africa, released the final feasibility study (DFS) report for the Songwe Hill rare earth mine project in Malawi, marking that the exploration and development of the project has reached an important milestone. milestone.The Songwe Hill project, located 90 kilometers from the commercial center of Blantyre, is the cornerstone of Mukange's integrated strategy of mining, smelting and recycling, and will provide support for its proposed separation plant in Poland, as well as its operations in the United Kingdom and Germany. Supplement to rare earth permanent magnet recycling plant.At the beginning of the year, Mukange announced that it has trial-produced praseodymium neodymium carbonate products using raw materials from the Songwe Mountain project.DFS is based on conventional open-pit mining and adopts grinding-flotation-hydrometallurgy process to produce mixed rare earth carbonate products.According to the DFS report, the Songwe Mountain Project has a Proven and Probable Ore Reserve of 18.1 million tonnes with a total rare earth oxide (TREO) grade of 1.16%.As proposed by DFS, the construction investment of the Songwe Mountain project is US$277 million (excluding the emergency fund of US$34 million), including mine development, mineral processing facilities, tailings dams and related infrastructure. The project is expected to start mining in February 2025, with a mine life of 18 years. The dressing plant will be put into operation in July 2025 and will reach production in September of the same year.Once full production is reached, the Songwe project can produce an average of 5,954 tons of rare earth oxides per year in the first five years. Including praseodymium neodymium oxide 1953 tons / year, dysprosium terbium oxide 56 tons / year, the total grade of rare earth carbonate 55%. The project's annual earnings before interest, tax, depreciation and amortization (EBITDA) can reach $215 million. From year 6 to year 18, the production of mixed rare earth carbonate is expected to be 4081 tons/year.The results of the feasibility study show that according to the discount rate of 10%, the net present value of the project after tax is 559 million US dollars, the internal rate of return is 31.5%, and the payback period is two and a half years.The reserves of this project have the possibility of further expansion. First, it is speculated that the amount of resources can be upgraded, and the second is that the nearby Nkalonje project has exploration potential.Since 2010, Mukange has been carrying out exploration work at the Songwe Mountain Project.This NPV does not include the project's contribution to the company's Pulawy Rare Earth Separation Plant in Poland, which will use misch carbonate from the Songwe Mountain project, allowing Mukang to pass an integrated Gain added value by transforming downstream businesses. The NPV also does not include the company's interest in the rare earth permanent magnet recycling business.With the release of the feasibility study report, Songguishan Rare Earth Mine has been confirmed as one of the few rare earth projects that have reached the final feasibility study stage. In accordance with international standards, the project has fully completed environmental, social and health impact assessments.William Dawes, CEO of the company, said: "The DFS is an important step forward for the company to become both a future mine and a supplier of recycled rare earths to meet the strong demand for rare earths in the green transition. ".At present, the company is trying to reach a final agreement on mine development with the Malawi government. Upon completion of the Pravi feasibility study, the company will announce the final feasibility study results for the rare earth mining and separation plant integration project.

CHALLENGER Exploration has completed the final 80,000 meters of its 204,000-meter drilling program at its Hualilan gold mine in Argentina, and its first announced resource of 2.1 million ounces is expected to grow significantly.  Current resources include 6.3 million tonnes of skarn-type ore at 5.6 g/t gold equivalent, or 1.1 million ounces of gold equivalent, and 41.4 million tonnes of intrusive/sedimentary ore at 0.8 g/t gold equivalent, or gold equivalent Equivalent to 1 million ounces.  “Importantly, we have discovered extensive high-grade skarn-type mineralisation, exceeding expectations, accounting for more than half of the total,” the company said. “Based on existing drilling results, more skarn deposits are expected to follow. It is found that the amount of resources will be greatly increased.”  The length of the gold ore body along the strike is 3.5 kilometers, and the current resources cover only 2.5 kilometers.

Argentine Mining Minister Fernanda Ávila recently attended the opening ceremony of the 11th "International Symposium: Lithium Mines in South America" held in Catamarca, northeastern Argentina. Argentina has a huge potential for developing lithium mines. The country's lithium carbonate output is expected to exceed 200,000 tons in the next five years, six times the current output (37,500 tons).Avila emphasized that Argentina is now the fourth largest lithium producer in the world after Australia, Chile and China; the country currently holds 6 lithium ore projects under construction and 2 lithium ore expansion projects, enabling it to reach the above-mentioned expected goals. In addition, the country is committed to the development of an inclusive mining industry that focuses on environmental protection. Argentina’s Ministry of Productive Development (Ministerio de Desarrollo Productivo) recently launched the Community Open National Mining Working Group (MEMAC) Have a conversation. In early May this year, the Argentine government launched the Community Open Mining Activity Information System, which aims to visualize the mining status and current projects using quantitative data on the impact of the mining industry in each province. There are indications that the Argentine government supports the development of the country's mining industry.Avila pointed out that there are 1,375 mining projects in Catamarca province, with 1,400 mining employees, an increase of 198 in the past two years. The mining industry pursues high quality, high output, multi-province participation, and more radiation education, engineering, and infrastructure fields, which can better improve the quality of life of the people.The representatives attending the seminar came from various Argentine provincial governments, provincial mining departments, lithium mining companies, professional consulting companies, technical institutions and domestic and foreign mining institutions. Role positioning, as well as the birth of emerging technologies and industrial status in strategic lithium mining regions such as Argentina, Chile, the United States, China and Europe.
