Silver Ore Flotation Project — 100 TPD Plant Case from Dasen Mining

Silver ore typically occurs in association with other metals such as lead, zinc, copper and gold.
In industrial practice, the silver grade of run‑of‑mine ore is a key factor in selecting appropriate mining and processing methods.

Silver Ore Grade Classification

To simplify evaluation, silver ores are generally divided into three categories:

  • High grade: above 200 g/t
  • Medium grade: 50 – 200 g/t
  • Low grade: below 50 g/t

Ore grade directly affects project economics and the chosen processing route.
For reference, the international silver price is highly volatile, ranging roughly from a low of around $44 per ounce to a high of nearly $114 per ounce. Such significant market fluctuations bring relatively high investment risks.
Since silver is mostly produced alongside other metals, the actual project profitability must account for the combined value of gold, copper, lead, zinc and other metals present in the ore.

Primary Treatment Method – Flotation

For sulphide ores containing mixed silver‑gold‑lead‑zinc mineralization, flotation is the most widely applied treatment method.
In simple terms:

  1. Crushing and grinding: Ore is ground to approximately 200 mesh to liberate individual mineral particles.
  2. Conditioning: Water and flotation reagents are added to form a slurry.
  3. Flotation separation: Air bubbles carry silver and heavy metal minerals to the surface for collection.
  4. Concentrate dewatering: Flotation concentrate is filtered and dried in preparation for smelting or refining.

This process has been proven efficient and reliable in plants worldwide.
As an example, the 100 TPD flotation plant designed and built by Dasen Mining Machinery uses this principle to recover and upgrade silver.
