Refractory Gold Ore Containing As & Sb, High Cyanide Consumption? Process Ideas For Reference
If your gold ore carries arsenic and antimony minerals, you may observe unsatisfactory gold recovery and higher reagent cost.
Arsenopyrite encapsulates fine gold particles; stibnite consumes cyanide during cyanide leaching.
Two onsite process approaches can help mitigate the adverse impact of arsenic and antimony.
We supply complete gold ore processing lines: crushing, grinding, CIP/CIL leaching systems.
Metallurgical ore test service available, feel free to message us on WhatsApp.

Today we’re talking about how zinc-bearing minerals affect gold cyanide leaching.
Zinc minerals in gold ore may exist in low quantities, yet they create big problems for cyanidation, mainly by consuming excessive reagents.
Take sphalerite (zinc sulfide) for example. When exposed to cyanide solution, it reacts and produces intermediate products such as sulfates and thiosulfates. These byproducts consume large amounts of cyanide and dissolved oxygen in the pulp.
Zinc oxides like smithsonite and zincite react even faster. They combine with cyanide directly and form zinc-cyanide complexes.
Once cyanide ions bind with zinc, they can no longer dissolve gold. Even if tests show residual free cyanide, the actual gold leaching capacity drops significantly.
Oxygen consumed during the reaction limits gold dissolution and reduces gold recovery rate.
Besides, accumulated zinc ions in solution will interfere with downstream processes such as zinc cementation and carbon adsorption. It increases zinc powder consumption, causes competitive adsorption on activated carbon and downgrades gold sludge quality.
✅ Key tip for on-site operation: If you process zinc-bearing gold ore, **conduct mineral processing test work before full production**. Flotation is recommended to remove zinc minerals in advance and eliminate interference. Only then can you start cyanide leaching to avoid costly failures.

🔍 Beneficiation of Titanium‑Zirconium Sand Deposits
Titanium‑zirconium placer deposits are mainly coastal & inland placers, formed by natural weathering and enrichment of primary ore. They are the major global source for ilmenite, rutile, zircon and monazite, featuring easy mining, low‑cost operation and high comprehensive recovery value.

The whole beneficiation workflow includes **Roughing + Cleaning**.
✅ **Roughing stage**: Mobile mining‑beneficiation complex. After desliming & screening, gravity separation by cone concentrator & spiral concentrator produces heavy‑mineral mixed rough concentrate.
✅ **Cleaning (Refining) stage**: Mostly stationary plant combining wet & dry separation.
Wet processes: gravity separation, wet magnetic separation, reagent washing and flotation.
Dry processes: multi‑stage magnetic separation, electrostatic separation, plus pneumatic shaking table for final purification.

We deliver one‑stop customized mineral processing solutions for titanium‑zirconium placer projects.
Share your ore condition, feed capacity & site requirements, we will work out your tailored process proposal.

Lead-Zinc Ore Beneficiation Combined Flowsheet

Normally, lead-zinc ore has good floatability, and qualified concentrates can be obtained by flotation alone.
For ores with poor floatability or complex ore properties, combined beneficiation processes are required.

✅ **Sulphide Lead-Zinc Ore**
When lead and zinc are closely intergrown with fine grain size, separation is difficult. The ore can adopt the **mineralurgy-metallurgy combined process**: produce bulk lead-zinc concentrate via flotation, then smelt in an Imperial Smelting Furnace (ISP). It improves overall technical indicators and cuts operating costs.
Case: Fankou Lead-Zinc Mine & Shaoguan Smelter.

✅ **Oxidized Lead-Zinc Ore**
The primary method is sulphidizing flotation (sodium sulphide for sulphidization before flotation).
Optional combined flowsheets: dense medium-flotation, flotation-hydrometallurgy, roasting-flotation.
Another typical flowsheet: flotation-gravity separation-flotation-gravity separation (Datun Concentrator, Yunnan Tin).

We provide complete process design and equipment solutions for lead-zinc mineral processing plants.
