Nickel sulfide ores are one of the important sources of nickel, mainly composed of nickel-iron sulfide ((Ni,Fe)9S8), millerite (Ni3S2), and other nickel-containing sulfides. Because these minerals usually coexist with other metal sulfides (such as copper, cobalt, platinum group metals, etc.), and are often accompanied by a large amount of gangue minerals, appropriate ore dressing processes are needed to improve the grade and recovery rate of nickel. Currently, common methods include flotation, magnetic separation, gravity separation, oxidation roasting-leaching, and bioleaching.

    • Q: What are the business scopes covered by KETAI?
      A:Our core business encompasses three major segments: 1.First, global trade of non‑ferrous metal ores, including the procurement and sales of gold, silver, copper, lead, zinc, and other mineral products; 2.Second, R&D and sales of beneficiation reagents – in partnership with our strategic partner Yantai Hengbang Chemical, we provide a full range of high‑performance reagents such as collectors, frothers, and depressants; 3.Third, EPC general contracting services, offering an integrated solution that covers “ore dressing testing – engineering design-equipment manufacturing – construction and delivery”.
    • Q: Can you provide ore dressing test services?
      A:Yes. Our company has a complete ore dressing test platform that can simulate on‑site operating conditions for reagent validation. The service workflow includes: sample submission → ore analysis → reagent screening → test verification → formulation recommendation → on‑site commissioning. The entire process usually takes 20–30 working days, depending on the complexity of the ore.
    • Q:How can I start business cooperation with your company?
      A:You can submit your requirements through the “Online Inquiry” channel on our official website, or directly contact our business department. Upon receiving your inquiry, we will arrange for dedicated professionals to get in touch with you, to understand your specific product needs, technical specifications, and cooperation intentions.
    • Q: How do you ensure product quality?
      A:The company strictly follows international quality standards and implements fullprocess quality control from the procurement of raw materials to final product dispatch. For beneficiation reagents, we cooperate only with qualified manufacturers in accordance with the scope and term of our hazardous chemicals business license, so as to ensure consistent and reliable quality.
    • Q:What about your aftersales service system?
      A:We provide comprehensive technical support and aftersales service. For beneficiation reagent customers, we offer onsite reagent suitability testing and process optimisation solutions at mines around the globe. For EPC project clients, we deliver fullcycle services from construction through to final handover.
