Controlling particle size during crushing and grinding is not merely a mechanical step — it directly determines how much gold is exposed to cyanide solution, how quickly leaching occurs, and how much energy, reagents, and time the entire operation consumes. This article explains scientifically why particle size is a defining factor in gold cyanidation performance, and how optimal grinding and crushing practices maximize recovery while minimizing operational expenses.

Tambayoyin da Ake Yawaita Yi (FAQs)

Q1: Menene girman ƙwayar ƙwayar da ta dace don ƙarewar Zinariya ta cyanid?

A: While it varies depending on the specific geology of the ore, most hard rock gold cyanidation processes require the ore to be reduced to a highly fine state (often 80% passing 75 microns) eventually. The goal of the crushing plant is to prepare the feed as fine as physically possible—typically reducing it to 10mm-12mm—to make the final liberation process highly efficient.

Q2: Me ya sa bai kamata in yi amfani da injin karyawa na tasiri wajen karyar gwal na farko ba?
