Mercury ore primarily yields mercury metal and cinnabar, with China’s production mainly focused on mercury. Cinnabar, a mercury sulfide mineral, is valued in chemical and medicinal applications. Mining liquid mercury is relatively simple. Cinnabar is a red mercury sulfide mineral with a specific gravity of 8.1-8.2 and good natural flotation. This guide explores the beneficiation and purification processes for mercury ore, tailored to different ore types and their unique characteristics.
Pabrik pengolahan merkuri adalah jalur produksi untuk pemurnian dan pemurnian bijih merkuri. Namun, metode dan proses pemurniannya juga berbeda menurut jenis bijih merkuri yang berbeda. Oleh karena itu, ia membagi pabrik penerima bijih merkuri menjadi berbagai jenis. Ada jalur produksi pemisahan gravitasi, jalur produksi flotasi, dan jalur produksi gabungan gravitasi-flotasi.
Jenis Bijih Merkuri
Struktur bijih merkuri relatif kompleks, termasuk disebarluaskan, berbintik-bintik, dan masif. Kita bisa menggunakan satu pemisahan gravitasi untuk bijih merkuri yang sangat besar manfaat untuk mendapatkan indikator yang lebih tinggi. Gunakan flotasi untuk bijih merkuri yang disebarluaskan manfaat untuk mendapatkan indeks manfaat yang tinggi. Dan gunakan metode pemisahan gravitasi gabungan dan proses flotasi untuk bijih merkuri kadar rendah berbintik-bintik penerima manfaat.
Bagaimana Cara Memanfaatkan Berbagai Jenis Bijih Merkuri?
MBijih merkuri asesif dan bijih merkuri berbintik-bintik: The beneficiation is very simple. According to hand selection and gravity separation can get good beneficiation indicators. Sometimes, to reduce production costs and improve the mineral processing index, speckled mercury ore is also treated by a gravity separation-flotation combined process. The gravity separation process discards a large amount of waste rock in advance on the premise of ensuring the recovery rate, reduces the cost and equipment investment of subsequent grinding and flotation, and improves the effective working speed of the subsequent process. The flotation method is used to purify the coarse gravimetric concentrate to obtain the final product. This process is most suitable for the beneficiation of speckled mercury ore.
Bijih merkuri yang disebarluaskan: Due to the mutual dissemination of mercury minerals and waste rock, it must grind disseminated mercury ore to break the conjoined organisms to extract mercury minerals. However, the particle size of the ground mercury minerals is very fine, and the gravity separation method can no longer be processed. Even so, flotation of lower-grade mercury ore still has high economic returns due to the higher added value of mercury ore.
The metode pemisahan manual is based on the difference in color, shape, and other characteristics between mercury ore and waste rock. It has the features of low production cost and high concentrate grade, but it can’t be used for the beneficiation of medium and fine-grained mercury ores. The indicators are also unstable, and the labor intensity of workers is relatively high. The metode pemisahan gravitasi cocok untuk memproses bijih merkuri berbintik-bintik dan bijih merkuri tertanam berbutir kasar. Ini memiliki keuntungan dari efisiensi manfaat yang tinggi, investasi peralatan kecil, biaya operasi rendah, dan tidak ada pencemaran lingkungan. Pemulihan bijih rendah. Itu metode flotasi is mainly used to extract disseminated mercury ore. Due to the high floatability of mercury sulfide ore, the flotation method often can achieve higher beneficiation indicators. The purity and recovery rate of the concentrate can meet the ideal requirements. Because the equipment of the flotation process investment is large, it has high operating costs and certain environmental pollution.
Proses Pemanfaatan Bijih Merkuri
The mercury ore beneficiation process is mainly divided into the gravity separation process, the flotation process, dan the gravity separation-flotation combined process.
- Proses pemisahan gravitasi bijih merkuri adalah menghancurkan - penyaringan - jigging - meja goyang.
- Proses flotasi bijih merkuri adalah crushing – screening – grinding – classification – stirring – flotation – filtering.
- Proses gabungan dari pemisahan gravitasi bijih merkuri dan flotasi adalah: crushing – screening – gravity separation – dehydration – grinding – classification – stirring – flotation – tekan filter.

Dalam proses pemisahan merkuri, peralatan yang biasanya kami gunakan dalam pemisahan gravitasi meliputi meja goyang dan konsentrator jig. Konsentrator jig menangani bijih berbutir kasar, dan meja goyang menangani bijih berbutir halus. Proses flotasi yang kami gunakan adalah mesin flotasi.
Meja Goyang
The meja pengocok dibagi menjadi pengocok pasir kasar, pengocok pasir halus, dan pengocok lumpur bijih.
Ukuran partikel pengumpan dari pengocok pasir kasar bisa 2mm, jumlah pengumpanan per jam antara 30-60 ton, dan konsentrasi pengumpanan 25-30%.
Ukuran partikel pengumpan dari pengocok pasir halus bisa 0,5 mm, jumlah pengumpanan per jam antara 10-20 ton, dan konsentrasi pengumpanan adalah 20-25%.
Ukuran partikel pengumpan bijih dari pengocok lendir bisa 0,15 mm, laju pengumpanan bijih 15-25 ton per jam, dan konsentrasi pengumpanan bijih 15-25%.
Konsentrator Jig
Ada tiga jenis konsentrator jig: bergerak ke samping, bergerak ke bawah, dan bergerak ke samping. Model dan gaya yang berbeda memiliki perincian pengumpanan dan kapasitas pemrosesan per jam yang berbeda. Jika Anda ingin mengetahui detailnya, Anda dapat berkonsultasi dengan teknisi penjualan.
Mesin Flotasi
Ada dua jenis sel flotasisel flotasi pengadukan berisi udara dan sel flotasi pengadukan mekanis.
Model mesin flotasi pengaduk mekanis adalah XJ, JJF, XJQ, SF, ring-shot, dll;
The air-filled stirring flotation machine models include CHF-X, BS-X, XJC, KYF, XCF, BS-K, etc.
Optimizing Mercury Recovery: Key Considerations
- Hand Sorting: Manual separation works for high-grade ore but is labor-intensive.
- Grinding Fineness: Disseminated ore must be finely ground for efficient flotation.
- Environmental Concerns: Flotation tailings require proper waste management.
Which Process is Right for You?
- High-grade massive ore? → Pemisahan gravitasi (cost-effective).
- Low-grade fine ore? → Flotasi (higher recovery).
- Mixed ore types? → Combined gravity-flotation (balanced approach).
