Executive Summary
This technical report details the processing methods and operational performance of the Palito Mining Complex in Pará State, Brazil, operated by Serabi. The facility processes ore from both the Palito and São Chico mines with a plant capacity of 500 tonnes per day. The flowsheet is designed to handle complex ore types, utilizing a combination of crushing, grinding, copper flotation, and carbon-in-pulp (CIP) cyanidation to recover gold and silver values.
Key operational highlights include the integration of an ore sorting circuit to upgrade low-grade Palito ore prior to grinding, enhancing overall recovery efficiency. The São Chico ore is processed through a separate grinding circuit featuring gravity concentration and intensive cyanide leaching. The combined tailings from these circuits undergo CIP cyanidation, with gold and silver adsorbed onto activated carbon before elution and electrowinning to produce a final doré product.
The report provides comprehensive data on equipment specifications, consumable requirements, and operating performance from 2017 to 2022. Gold recovery rates have remained consistent, averaging around 92% for milled ore, with the ore sorter demonstrating significant value in upgrading low-grade material. The facility employs robust cyanide detoxification processes to ensure environmental compliance before tailings disposal.
