Targeting Gold Recovery Inefficiencies: The Modern Stamp Mill Solution

Are you managing gold recovery operations where inconsistent particle liberation, боловсруулсан тонн тутамд эрчим хүчний зарцуулалт өндөр, and excessive downtime for liner and stamp maintenance are eroding your profit margins? Each hour of unplanned stoppage in a gravity concentration circuit can represent thousands in lost precious metal recovery. Are you questioning how to improve yield from complex ores while controlling operational costs? The evolution of a classic technology provides a reliable answer.

Бүтээгдэхүүний тойм: The Modern Chinese Stamp Mill for Gold Ore Processing

A contemporary Chinese stamp mill is a mechanized gravity concentration and crushing device designed for the liberation and recovery of free gold from ore. It operates through a controlled, repetitive dropping of heavy weights (марк) зуурмаг хайрцагт тэжээгддэг хүдэр дээр. This process crushes the material via impact, with water facilitating the washing of finer gold particles through an integrated screen onto concentrating tables or sluices.

Үйл ажиллагааны ажлын урсгал: 1) Ore is fed into the steel or cast iron mortar box. 2) Mechanically lifted stamps are released to drop onto the ore, crushing it by impact. 3) Flushing water carries the crushed slurry through a discharge screen. 4) The screened material flows to downstream concentration units (жишээ нь e., сэгсрэх ширээ). 5) Tailings are separated, and coarse oversize material can be recirculated.
Хэрэглээний хамрах хүрээ: Жижиг, дунд хэмжээний уул уурхайн үйл ажиллагаанд нэн тохиромжтой, намжн сарын станц, or processing centers targeting alluvial or hard rock gold ores where free milling gold is present. It serves as a primary ore reduction and initial liberation step.
Хувьсгал: Not suitable for refractory ores requiring chemical leaching. Efficiency declines with very high clay content or excessively hard abrasive materials without precrushing.
