Modernization and Optimization of Existing Concentrators

Existing mineral processing concentrators frequently face operational challenges that impact profitability. These issues often stem from factors such as:

Suboptimal process configurations and flowsheets.
Mismatched or inefficient production equipment.
Unreliable or unstable production lines causing downtime.
Insufficient levels of automation and process control.
Utilization of outdated technology unsuited for evolving ore characteristics or modern efficiency standards.

To address these challenges, ZONEDING deploys specialized technical teams to the client’s site. Collaborating closely with the owner, we conduct thorough on-site assessments to precisely identify operational bottlenecks, inefficiencies, and areas for improvement. Based on these diagnostic findings, ZONEDING develops and implements targeted, data-driven action plans focused on enhancing overall plant efficiency, reducing operational costs, and maximizing the economic performance and potential of the existing facility.

Proven Expertise in Mineral Processing Plant Design

ZONEDING possesses extensive design expertise within the mineral processing sector, demonstrated through the successful execution of numerous international projects. Our design portfolio encompasses a wide range of plant types, including:

• Crushing and grinding circuits
• Gold and silver processing plants (including heap, vat, and cyanide leaching)
• Placer gold recovery plants
• Gold and silver desorption, electrowinning, and smelting facilities
• Flotation plants (for base metals, precious metals, industrial minerals)
• Gravity concentration and upgrading plants (reselection)
• Mineral concentration, dewatering, filtration, and water recovery systems
• Tailings resource recovery and reprocessing plants
• Mobile and modular concentrator units

ZONEDING’s comprehensive engineering design services cover the full project lifecycle, including conceptual/scheme design, preliminary design, and detailed engineering design ready for construction.
