From Alaska to West Africa, SRS Crisafulli dredging experts are busy installing dredges and training operations personnel at producing gold mines.  Nearly all operating mines have overflow lagoons and impoundments for the collection of particulates, overflow mud, and tailings.  Typically the lagoons are lined, and are operated as part of a water treatment system to ensure all water released from the mine meets environmental regulations.  In many cases the water and particulates are acidic in nature and require specialized equipment adaptations such as stainless steel construction to ensure longevity.

Gold mine companies find SRS Crisafulli Flumps to be an excellent choice for a variety of projects.  Small, remote controlled, extremely productive, and a high value, Flumps perform well across a wide range of applications and environments.  Project applications at gold mines are primarily for the purpose of either dredging waste sediments for dewatering and disposal or for the purpose of recovering gold from tailings or overflow sediments.  When used to dredge for disposal the sludge is sent to centrifuges or geobags, dewatered, and then disposed of.  When used to dredge for gold recovery the tailings are sent to a processing mill so the sediments can be re-processed.  In some cases tailings are recently produced, and in other cases the tailings are historical in nature yet still contain recoverable amounts of gold.

One characteristic shared by both Alaskan gold mines and West African gold mines is remoteness.  These operations, encompassing surface mines and underground mines, are a testament to the abilities of companies to build and sustain small cities in some of the most inaccessible locations in the world.  Alaskan locations are noted for their short summer periods and long duration cold winters while West Africa, south of the Sahara desert, is tropical in nature, with high temperatures and humidity.  Regardless of the environment, SRS Crisafulli’s attention to detail, rigorous manufacturing standards, and ability to customize solutions to the most demanding requirements results in long-lasting, dependable dredges.
