A Case Study of Enhanced Sulfidization Flotation of Lead Oxide Ore
The refractory lead oxide ore has become an important source of lead metal with the continuous depletion of lead sulfide minerals. Lead oxide ore is of poor floatability and there are few cases to concentrate it successfully. In this study, the sulfidization-xanthate flotation method is applied for the beneficiation of lead oxide ore @article{Liu2011ImprovingCF, title={Improving copper flotation recovery from a refractory copper porphyry ore by using ethoxycarbonyl thiourea as a collector}, author={Guang-yi Liu and Zhong Hong and Liu-yin Xia and Wang Shuai and Zhenghe Xu}, journal={Minerals Engineering}, year={2011}, volume={24}, pages= {817-824Improving copper flotation recovery from a refractory copper

Study on Beneficiation of a Low-Grade Refractory Copper Oxide Ore
Experimental investigation was conducted on a low-grade copper ore in Tajikistan with grade of 0.89% and oxidation rate of 99%, which belongs to refractory oxide copper with low-grade and high oxidation rate. According to the property of process mineralogy, using vulcanization xanthate flotation process, determined once rough concentration, three The possibility of applying a combined concentration and metallurgical method for processing low-grade and refractory copper–nickel ores was considered. The resulting rougher and scavenger flotation concentrate contained 2.07% nickel and 0.881% copper at a recovery of 85.44% and 89.91%, respectively.

Copper Beneficiation Process JXSC Mineral
Copper Flotation. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.The low-grade refractory ore used in the experiments was obtained from Xiaonangou in Henan province. Approximately 350 Kg ore was homogenized and split into 1-kg representative sub-samples. During the ore preparation, a 100-g sub-sample was taken for head-grade chemical analysis (table1).

Leaching characteristics of copper refractory ore in sulfate media
Refractory copper ores (CROs) in central Africa contain copper minerals that are locked up in a micacious solid matrix or associated with carbonate, sulfide and phosphate minerals. Several researchers have reported that the recovery of copper from CRO material by an acid-leaching process is not economically feasible, due to the A task of a refractory oxide copper ore in Yunnan has been studied, the grade of copper is 2.76% in crude ore. This ore has high oxidation and deep combination, the oxidation ratio is 42.32% and the combination ratio is 33.01%, so it is difficult oxide copper.

Study on the pre-treatment of oxidized zinc ore prior to flotation
Abstract. The pre-treatment of zinc oxide bearing ores with high slime content is important to ensure that resources are utilized optimally. This paper reports an improved process using hydrocyclone de-sliming, dispersion reagents, and magnetic removal of iron minerals for the pre-treatment of zinc oxide ore with a high slime and Separation flotation method can also achieve good results for refractory oxidized copper ore. It is to crush the mineral to a certain particle size, mix 0.1% ~ 1.0% salt and 0.5% ~ 2.0% pulverized coal, and heat it to about 900 ℃ in oxygen isolation. The copper in the ore will precipitate on the carbon particle surface in metal state.How to Beneficiate Oxidized Copper Ores? JXSC Machine
