Tingkat Operasi Melebihi Harapan di Bawah Substitusi Tembaga Katoda-Limbah, Batang Tembaga Katoda Memecahkan Radius Transportasi?

Chile's central bank reported on September 1 that the July Imacec economic activity index fell 1.5% year-on-year on an unadjusted basis. On a seasonally adjusted basis, the index fell 2.1% year-on-year and 1.7% month-on-month, marking the steepest monthly decline since 2022. The bank attributed the drop mainly to mining, which fell a significant 9.3%, primarily due to weather conditions, followed by lower ore grades and equipment maintenance that disrupted normal production operations. Many of the affected mines are copper-molybdenum associated deposits. Since molybdenum concentrate is recovered as a byproduct of the flotation process used to treat copper sulfide ore, the disruption to processing plants also curtailed molybdenum output.

Anax Metals telah meluncurkan studi kelayakan pelindian tumpukan di proyek tembaga-seng Whim Creek di Australia Barat, menilai rute pemrosesan kedua di samping konsentrator yang direncanakan. Uji kolom CSIRO baru-baru ini mencapai ekstraksi tembaga 77–80% dan ekstraksi seng lebih dari 90% dari bijih kadar rendah. Studi tersebut, yang ditargetkan selesai pada kuartal pertama 2027, akan mengevaluasi potensi produksi dan pemasaran katoda tembaga dari infrastruktur pelindian tumpukan dan SX-EW yang telah diizinkan.
