Abstract: The study developed new, novel, and cheaper materials as micronutrients for plants. These studies showed that some copper ore can be utilized as a cheaper source of copper micronutrients. This method would be economically feasible for agriculture. The study has shown that roasting increased the recovery of copper from different ores differently. As the roasting time and temperature increase, the leaching of copper will also increase. The leaching of copper maximum in a sample was in the order of leaching of copper in three ores is as Sample C>sample D>Waziristan chalcopyrite. The experiments showed that the untreated raw oxidized copper ore show significant leaching which is 9.5% for saline and 35.5% for fertile soils respectively. This is an important finding which showed that oxidized copper ores can directly be used as slow-release micronutrients. A cheap process based on grinding to 200 mesh would be feasible. It is further seen that roasting at 750oC is suitable for treating sulfide ores. The acidification has shown much improvement in leaching and providing micronutrients to the soil.
