This industrial coarse copper sulfide is manufactured via dry-phase mineral synthesis, delivering stable effective copper content. Its controlled free sulfur residue helps curb excessive sulfur dioxide release during high-temperature smelting. The coarse granular powder reduces floating loss inside flotation cells, making it well suited for standard flotation processes adopted by non-ferrous metal concentrators.

Industrial Grade COPPER(II) SULFIDE｜CAS#1317‑40‑4
H2: Product Overview
Industrial‑grade copper(II) sulfide is manufactured by dry‑phase mineral synthesis process. It features stable effective copper content, while controlled free‑sulfur residue restrains excessive sulfur‑dioxide overflow under high‑temperature smelting conditions. Its coarse granular powder minimizes floating loss within flotation tanks, making it highly compatible with conventional flotation workflows operated by non‑ferrous metal concentrators.
H2: Product Application
H3: Mineral Processing & Flotation Industry
It functions as a high‑performance flotation activator for sulfide ores of copper, zinc and lead. By improving the hydrophobic property of target mineral surfaces, it effectively lifts the concentrate recovery rate for ore‑dressing plants.
H3: Non‑Ferrous Metallurgy Field
Acts as critical intermediate feedstock for non‑ferrous copper smelting. It participates in the production chain for electrolytic copper and multiple inorganic copper‑salt chemical syntheses.
H3: Potential Extended Industrial Usage
Besides mineral beneficiation and smelting, this product can also serve as raw material for related sulfide‑based chemical preparation for auxiliary industrial projects.
H2: Key Product Strengths
H3: Stable Batch‑to‑batch Performance
Strict process control over dry‑phase mineral synthesis guarantees consistent effective copper content from batch to batch. Free‑sulfur residuals are tightly regulated to avoid excess sulfur‑dioxide emissions during smelting operations.
H3: Optimized Granular Property for On‑site Operation
Coarse‑grained powder greatly reduces floating loss in flotation cells. It adapts well to existing production equipment without extra modification for most mineral‑processing plants.
H3: Long‑term Supply Reliability
Annual long‑term supply contracts are available for large‑scale mineral concentrators and smelting enterprises, securing stable raw‑material supply for continuous mass‑production schedules.
H2: Packaging, Storage & Transportation
H3: Standard Bulk‑shipping Packaging
Standard packing: 25 kg woven bag equipped with PE inner liner for bulk shipment. The inner PE liner delivers moisture‑proof performance, and outer woven bags offer mechanical protection for sea and land freight. Customized packaging specifications are negotiable for large‑volume orders.
H3: Storage Recommendations
Store in cool, dry and ventilated warehouse. Keep sealed and avoid prolonged exposure to humid air. Keep apart from strong oxidants to prevent unexpected chemical degradation.
H3: Transport Notes
Ship as general industrial chemical goods. Please refer to MSDS for complete handling guidance. We support FCL and LCL ocean shipment for overseas bulk cargo.
H2: Delivery Schedule
H3: In‑stock Items
Shipment within 2‑3 working days upon payment confirmation.
H3: New‑production Orders
Production lead‑time: 7‑10 working days for freshly manufactured batches.
Remark: Above lead‑time excludes international ocean transit time; schedule may be slightly adjusted during peak production or logistics
seasons. We will send real‑time progress updates for each order.
