A method for the analysis of zinc oxide phase content in sulfide ore was studied. On the basis of the characteristics of each phase component, the sulfide ore sample was leached twice with NaOH and acetic acid-ascorbic acid, respectively, so that the oxide mineral and zinc oxide were dissolved completely. The leaching rate of zinc oxide phase was up to 98 Vo. Moreover, the dissolution of zinc sulfide phase was effectively inhibited, solving the problems of selective leaching and determination for zinc oxide.

K-means, and self-organizing map and the feature selection methods based on coefficient of variation and simple T-test were integrated. To evaluate the performance of the Samcluster system, the Samcluster was applied to four expression datasets COLON, LEUKEMIA72. LEUKEMIA38, and OVARIAN. The results show that there are only 5, 1,0, and 0 samples misclassified, respectively. We conclude that the proposed scheme. SamCluster. is an efficient method for automatic discovery of sample classes using gene expression profile.
