Alluvial gold mines is various in kinds and widely distributed. According to the transport distance, the alluvial gold mines can be divided into residual placer gold, slope placer gold mine, alluvial placer gold mine, riverbed impact placer gold mine, and coastal placer gold mine. Among them, the riverbed impact placer gold mine is common. According to handling force medium, the alluvial gold mine can be divided into aeolian placer gold mine, ice-forming placer gold mine, and aquatic placer gold mine. According to the era of transport, the alluvial gold mine can be divided into deep placer gold deposit, terraced placer gold mine, and river beach placer gold mine. There is very low content gold in the alluvial gold mine. It needs all kinds of gold processing equipment for processing and enrichment. The gravity separation has the characteristic of high-efficiency, energy-saving and environment-friendly. It is the main alluvial gold mining method. Generally, gold and various kinds of associated heavy minerals can be recovered through gravity separation. Then gold and associated heavy sand minerals can be separated through gravity separation, flotation, magnetic separation, and electrostatic beneficiation.
Based on the above problems, the gold tailings disposal methods and comprehensive utilization of gold tailings is extremely urgent. At present, the common gold tailings disposal methods and comprehensive utilization mainly include the following ways: gold tailings reprocessing method, gold tailings dry stacking method, production of building materials, mine filling, reclamation and making field.
At present, the common chrome extraction processes mainly include gravity separation, magnetic separation, electric separation, flotation, gravity-magnetic separation process. Below, let’s take you to learn about each chromite ore processing process.
According to the type of deposit, feldspar can be divided into pegmatite-type feldspar, white granite-type feldspar, granite-type feldspar, and feldspar placer, etc. Due to the different types of ore deposits and ore properties, the beneficiation process of each feldspar is also different.
Mica is a common silicate mineral with a layered structure and monoclinic crystal system. This article will introduce 6 mica extraction processes used in actual production.
Gold elution process is a technique used to extract precious metals from ore, usually associated with gold mining. This article will teach you more about gold elution process.
Gravity separation method is very common in the field of mineral processing. This article will help you to further understand the principle, process, types, characteristics and influence factors of gravity separation method.
Common graphite processing methods mainly include flotation, gravity separation, electric separation, selective flocculation, alkali-acid method, chlorination roasting and high temperature roasting method.
Magnetic separation is one of the main beneficiation methods of iron ore extraction. This article will analyze 4 key points of operation to teach you how to increase efficiency of iron ore magnetic separation process.
Gold mining equipment refers to the machine that extracts gold ore from the earth's crust and separates gold from other gangue minerals. Small scale gold mining equipment is mainly used in small-scale gold mines and mobile gold processing plants.
However, with the extensive use of quartz resources, the high-quality crystal and gangue quartz are increasingly reduced, and low-grade quartz resources are paid more and more attention. Let’s see the three low-grade quartz ores beneficiation method-natural quartz sand, quartz sandstone, and silty quartz.
Common iron ore includes magnetite, hematite, limonite, and siderite. Here the limonite separation process includes the single separation process and combined separation process.
Gold ore flotation is a commonly used process in gold beneficiation plants. It is mainly suitable for processing gold ore with finer particles, sulfide gold-bearing quartz vein ore with good floatability, and processing polymetallic gold-bearing sulfide ore and graphite-bearing gold ore ores.
At present, common quartz sand iron removal methods include mechanical scrubbing, magnetic separation, froth flotation, and acid leaching.
At present, wolframite mineral beneficiation is generally divided into coarse-grained and fine-grained beneficiation, and we will mainly introduce these two aspects below.
