Sydostasien|Myanmar Gold Mine Distribution och Sand Gold Production Line Configuration
Myanmar is located in the western part of the Indochina Peninsula in Southeast Asia, between the Indian Plate and the Eurasian Plate, with a complex regional tectonic background and superior mineralization geological conditions. The main minerals in Myanmar include antimony, chromium, nickel, copper, gold, lead, zinc, silver, tin, and tungsten.

Guldmineraliseringsområdena i Myanmar kan delas upp i tre huvudsakliga metallogena provinser (kallas A, B och C nedan) (som visas i figuren) . är en mineraliseringsprovinst i Wunzo-felet, och Shallow lågtemperatur hydrotermal guldbjörn är det i en serie som är en serie av NE-Volen och Sediment-sediment rocks. The mineral deposits discovered in this province include Bamauk, Pinlebu, Wuntho, Kawalin, and Kanbalu. The Kyaukpahto mine, located in the mineralization province, is the only mine in Myanmar that uses modern technology to mine gold. The ore body is located on the southeastern edge of the Wuntho -felblock, och guldmineralisering distribueras längs NW -riktningen, utvecklad i kvarts av starkt silicifierat och vinklat sandsten .
The B mineralization province is located on the western and northern edges of the Shan Tanintharyi belt, and gold mineralization occurs in the early Cambrian ChaungMagyi shallow metamorphic sedimentary rock sequence and the older Mogok sequence of high-grade metamorphic rocks. The gold deposits discovered in this mineralization province include Thabeikyin, Phayaung Taung, Kyaukse Ye Yeman, and Pyinmana. Among them, the Phayaung Taung deposit is located 40 km north of Mandalay, with quartz as the gold bearing mineral and an ore resource of approximately 3 million tons, with a grade of 4.8 μ g/g. The ore deposit is a layer controlled ore body and is believed att ha genomgått återaktivering och anrikning av guld under metamorfiska förhållanden med låg kvalitet . Guldmineraliseringen i C-mineraliseringsprovinsen är relaterad till de vulkaniska stenarna i Northern och Western MyanMar, men det finns fortfarande lite forskning om detta yta) The gold mineralization of the HmaingdaingTaung deposit east of Lemyethna and Tagaung is developed in the blue gray quartz veins of volcanic rocks, some of which are accompanied by copper mineralization. In addition, the Kyaukphyu area near the Shwegu region of Kachin state is also rich in gold deposits, with gold mineralization located at the contact zone between volcanic rocks och Gabbro Rocks.
Sand gold production line 1. Overview of sand gold production line Sand gold mining is a complex system engineering that requires the design of reasonable process flows based on the characteristics of different ore bodies and production scales. The sand gold production line described in this article adopts a process flow of "ore washing+screening+jigs/agitation chutes+sticky gold chutes+shaker, centrifuge optional", which balances processing efficiency and recovery rate, and is suitable for mining operations of small and medium-sized sand gold mines. 2, Core equipment configuration and process flow 1 The ore washing process is the first step in sand gold processing, with the main purpose of separating gold bearing materials from clay and gravel. According to different processing capacities, small production lines can be selected: using drum washing machines with a processing capacity of 10-50 ton/timme . Medium produktionslinjer: utrustade med tvättmaskiner med en bearbetningskapacitet på 50-200 ton/timme . stora produktionslinjer: med en kombination av vibrerande tvättskärmar med en processkapacitet av 200-500 tons/timme {{15}. {15}) sprida material samtidigt som man undviker förlust av finkornigt guld .
2. The screening equipment of the screening system is usually set up in two stages according to the subsequent process requirements: the first stage screening: 20-30mm aperture, and the second stage screening for separating large gravel: 2-5mm aperture. It is recommended to use a double-layer vibrating screen for separating medium and fine-grained materials, with an Övre skärm på 30 mm och en nedre skärm på 3 mm, som kan slutföra två screeningsteg samtidigt, spara utrymme och energiförbrukning . 3. re Select Core Equipment Configuration (1) Jig och Agitation Chute Selecture Jig: lämplig för bearbetning av material med ett partikelstorlek av 3-25 m, med en återhämtningshastighet med över 85%{12 {12 {Rekommendation för SAE CEOTALE AVSAGE JAGE JAGE JA) Fina guldpartiklar . Agitation Chute: Det har uppenbara fördelar med bearbetning 0.5-5 mm finkorniga material, spara vatten och energi, och är lämplig för vatten knappa områden .}}}}}}}}}}}}}}
For ores with high gold content, it is recommended to use a jigs in series with an agitation chute, first jigs and then chutes, to achieve full coverage of particle size. (2) The sticky gold chute, as an auxiliary recovery equipment, mainly captures the fine gold particles that escape during the front-end process. Using mercury coated copper plate or special velvet blanket lining, with a tilt angle of 10-15℃and a length of 3-5 meters. (3) The selection of the shaking table adopts a 6-S shaking table or a Yunxi shaking table to process the coarse concentrate obtained from the previous reselection, which can increase the gold grade to over 90%. For fine-grained gold Gruvor, det rekommenderas att använda ultra-fina skakningstabeller .
(4) Centrifuge (valfritt) Rekommenderad modell: Vattenjacka Centrifugal Beneficiation Machine Tillämpliga förhållanden: När innehållet av fina guldpartiklar i malmen är hög, rekommenderas det att konfigurera installationspositionen: vanligtvis placerad framför skakaren som en förvalsutrustning .
