Precious-metal extraction agent
Agent ES1099 — More Efficient, Less costly.
A product for controlled evaluation of selected ore and recycling feeds, supported by representative testing and project-specific technical support.
ES1099Product solution supported by testing and process control
About the Product
Operating Conditions Must Be Defined for Each Feed
EcoSafeChem offers a precious-metal recovery portfolio including Agent ES1099 and Agent ES1098 for selected project evaluation. The current Product & Application Overview covers ES1098 and ES1099 with separate document-control boundaries.
Dosage, time, particle size, pH and recovery route must be defined by metallurgical testwork. Catalogue values are starting points for testing and are not guaranteed industrial outcomes.
- Suitable for evaluation in heap, vat and agitated CIL/CIP circuits
- ES1098 ore-test reference: pH 11.0–11.5; do not exceed pH 12 when using lime
- Light-grey to light-brown granules or powder
- Protective gloves, clothing and eye/face protection required

All ApplicationsOre and Selected Recycling Feedstocks
Final operating conditions and dosage are selected only after representative testing.
Project Execution Model
Four Steps to Reduce Scale-up Risk
Feed Data Collection
Assays, mineralogy, grade, particle size and processing history are collected.
Test Programme Design
Agent concentration, pH, time, particle size and economic success criteria are defined.
Monitoring & Optimisation
Titration concentration, recovery, consumption and interfering-element behaviour are reviewed.
Technical Proposal & Supply
An operating range, recovery route, supply plan and HSE requirements are proposed.
Reference Data
Guidance Figures, Not Guaranteed Outcomes
The figures below are catalogue reference starting points and must be confirmed by project testwork.
