Overview

This research synthesizes copper nanoparticles from copper tailings, highlighting a novel recycling approach.

Key Points

  • The aim is to synthesize and characterize copper nanoparticles from copper tailings and reagent copper salt using sodium borohydride.
  • Used chemical reduction method for nanoparticle synthesis.
  • Pulverized copper tailing particles digested and analyzed via ICP-OES and IC.
  • Characterized nanoparticles using XRD, XRF, TGA, FTIR, BET, SEM, and TEM.
  • Cu identified as the predominant cation (1355.25 mg/L) and sulfate as the predominant anion (838.50 mg/L).
  • XRD confirmed crystalline structure of nanoparticles.
  • TGA showed thermal stability for synthesized nanoparticles at temperatures of 297.70°C and 311.37°C.
  • BET provided surface area measurements ranging up to 189.93 m²/g.
  • SEM and TEM indicated spherical shapes for all synthesized samples.
