Frequently asked questions

FAQs for precious metals recovery equipment

Following initial crushing and grinding of the ore, precious metals are recovered via a combination of processes that liberate the metal from the surrounding rock and allow its recovery. These processes may include gravity concentration, flotation, or cyanidation (leaching), carbon ADR systems, electrowinning, and Merrill Crowe systems. Recovered metals are often further refined to achieve the desired purity.

Precious metals are recovered from electronic waste (e-waste) using several methods designed to extract valuable metals from discarded electronic items. Common techniques include shredding and sorting of the e-waste into ferrous and non-ferrous metals, and other materials; pyrometallurgical or hydrometallurgical processes to separate the metals; and flash joule heating, which rapidly heats e-waste to vaporise metals for collection through condensation.

FLS offers a comprehensive range of equipment and processes for the recovery of precious metals, including complete carbon ADR and Merrill Crowe systems, cyanide leach, precious metals electrowinning and refining equipment, carbon regeneration kilns, mercury retort and abatement systems, and gravity concentration and intensive cyanidation systems. Our product portfolio is built on a heritage of industry pioneers, including AuTec, Dawson Metallurgical, Knelson Technologies, Ludowici, and Summit Valley Equipment & Engineering.
