Frequently Asked Questions


  • 1. Who are we?
    • ​Molibdenos y Metales is a Chilean company (Corporation), founded in 1975 upon the division of Carburo y Metalurgia S.A., taking the activity, in a visionary stance, of the production and sale of molybdenum oxide, ferromolybdenum and byproducts. Molymet is the main processor of Molybdenum and Rhenium concentrates in the world, with a worldwide processing share of approximately 35% and 70%, respectively. 

  • 2. What is Molybdenum? Where is it found?
    • Molybdenum is an essential metal from the biological point of view and is mostly used in alloy steels. It is a metal with a silver gray color, which does not exist in pure form in nature, and is usually found bound to other elements, as is the case of sulphide minerals (from which copper is also obtained), where Molybdenum Sulfide, MoS2 ("molybdenite") can be found. It is common for molybdenum to be regarded as a byproduct of a copper extraction operation.
      Deposits of molybdenum can be divided into two types:

      - Primary molybdenum mine: These mainly consist of molybdenite concentrate.
      - Secondary molybdenum mine: Molybdenum is found mainly as a byproduct of copper.

  • 3. What are its main uses?
    • Molybdenum is primarily used in special steel alloys (approximately two thirds of molybdenum used are used in alloys), where it significantly improves hardness, resistance to high temperatures and corrosion, increases durability and improves machinery efficiency. There are also applications of molybdenum in fertilizers, catalysts, lubricants, among others. The most relevant molybdenum products are: technical oxide, ferromolybdenum, ammonium dimolybdate (ADM), pure oxide and metallic molybdenum. Among its processes, Molymet extracts Molybdenum byproducts, Rhenium being the most important.

  • 4. What is Rhenium?
    • Rhenium is a transition metal rarely found in nature. Its main uses are when used as a catalyst and in supper-alloys in components with high temperature resistances, used in turbines and engines of the aeronautic industry, among others.

  • 5. What are the main business units of Molymet?
    • -Own Sales: Molymet purchases molybdenum concentrates (molybdenite) and uses its own technology for the treatment and processing of the concentrate, in order to product a wide variety of molybdenum products (from molybdenum oxide to pure products) and then sell them to various clients in the global market.
      -Tolling: Companies in the mining industry supply molybdenite to Molymet so it is processed and then returned to the companies as a marketable product. A fee is charged for this service.
      -Byproducts: As a result of the roasting and oxidation process to which molybdenum must be subject to for processing, Molymet extracts byproducts that are later marketed. These byproducts are rhenium, copper cathodes and sulfuric acid.
      -Efficiencies: Molymet has developed proprietary technology that allows it to improve on its oxidation and roasting processes, so, today, it is able to reduce metallurgic losses and achieve metallurgic earnings in its processes.

  • 6. How has Molymet focused its investments and expansions in recent years?
    • The company's strategy is materialized through 3 strategic axes:
      - Maintaining the global leadership of Molymet in the molybdenum industry, increasing its processing capacity in line with the growth in global demand.
      - Developing molybdenum products with higher added value, such as Metallic Molybdenum.
      - Adding new strategic minerals to its product portfolio, achieving greater diversification and taking advantage of market opportunities.
      Molymet is constantly concerned about expanding its processing capacity, increasing its efficiency through new technologies, offering products tailored to its clients and developing long term relationships with its suppliers and clients, hence achieving the strengthening and consolidation of the company’s position, its investors, clients and suppliers.

  • 7. In which countries is Molymet present?
    • Molymet currently has plants in 5 countries: Chile, Mexico, Belgium, Germany and China as well as commercial offices in England, China, the United States, Brazil, Peru and Chile. Molymet has a unique geographic diversification in the industry. The strategic location of its processing plants and commercial offices has allowed it to obtain advantages in terms of supply and reaching commercial advantages through a more complete and efficient service for its clients.

  • 8. What is the Real Estate business of Molymet?
    • Molymet, through its Real Estate subsidiary, San Bernardo, has among its assets a lot of 133 hectares, of which 123 hectares have walnuts. These hectares are located around the Molymet Nos plant (Green Strip), which is located in a 42.9 hectares lot. Together, both properties reach an approximate total of 175.9 hectares, which constitutes a lot with a great economic appeal, with a significant future potential.​
