(1) The organbentonite can adsorp xanthate and its oxidization products ── xanthatedCuprous and dixanthate.

(2) The xanthate derivative method, halogenated solvent method and amide LiCl method for preparing chitin fiber are introduced.

(3) The cerusite can be collected by xanthate without sulfuration, but the flotation index is not good enough.

(4) Sugarcane bagasse Cellulose Xanthate ( SCX ) can be synthesized by alkali cell use's reacting with carbon disulfide.

(5) Diethyldithiocarbamate was more better selective collector than Xanthate on galena.

(6) Kerosene and butyl xanthate were used as collectors in bulk flotation.

(7) Diethyl xanthate not only adsorbed chemically but also became dixanthogen on jamesonite surface.

(8) The cerusite can be collected by xanthate without sulfuration, however the flotation indexes are not good.

(9) In HCl medium, cotton cellulose xanthate absorb the solution where the abandoned electronics circuit board is dissolved by the king water.

(10) Chitin xanthate, cellulose xanthate and their blend solution belong to non-Newtonian fluid, where non-Newtonian Index increases and structure viscosity decreases with increasing solution temperature.

(11) Though xanthate, the traditional sulfide ores collector effective in collecting ability, its selectivity is not good.

(12) The effects of mass concentration, aeration rate, feeding mode, settling time on the biodegradation of butyl xanthate were investigated.

(13) A method for determination of trace lead in water by FAAS with slotted quartz tube after separation and enrichment with cotton cellulose xanthate is developed.

(14) Floatation experiment in Wushan Copper Mine shows that isopropyl xanthogen ethyl formate has higher recovery ratio and higher copper grade than xanthate when they are used as copper sulfide collector.

(15) The mechanism of removing heavy metal ions and the stability of sawdust cellulose xanthate were also discussed.

(16) The quantum chemical CNDO/2 method is used for calculating the reduced model of xanthate adsorption onto the minerals of copper sulphide or oxide.

(19) The combination ofthe two modified bentonite can improve the removal capacity of xanthate.

(20) MgSO4 and Epichlorohydrin has no impacts to the degree of xanthate acidification, but they can enhance the degree of crosslink and the insolubility.
