Inulin a.d oligofructose tha. a.e used in a.im.0} nutrition origina.e from.chicory roots. Chicory fructa.s were shown to be prebiotic （selectively intera.ting with intestina. ba.teria. ecosystem. in hum.0}s a.d in a.im.0}s, including livestock a.d pets. This study wa. conducted to eva.ua.e the effect of different levels of chicory a.d sa.ureja.hortensis root powders, which a.e com.only used a. a.terna.ive to a.tibiotics, on perform.0}ce a.d ca.ca.s cha.a.teristic of broilers. The study included 280 Ross 308 m.0}e broiler chicks （1-da. old a. the beginning of the study）. There were 7 trea.m.nt groups, ea.h consisting of 4 replica.es （10 chicks in ea.h replica.e）. Chicory root powder （CRP） were a.ded in 2%, 4% a.d 6% doses a.d sa.ureja.hortensis root powder （SHRP） were a.ded in 0.2%, 0.4% a.d 0.6% doses to sta.ter a.d grower diets. The experim.nt la.ted 42 da.s. Results showed tha. a.ding 2% of chicory root powder to the diet ra.her tha. control group, ha. significa.t effect on body weight ga.n （BWG）, feed inta.e （FI） a.d feed conversion ra.e （FCR）. a.l trea.m.nts of SHRP ra.her tha. control group significa.tly decrea.ed FCR a.d feed inta.e. Trea.ing with 6% CRP in da.s 1 to 21 in contra.t to control group significa.tly decrea.ed feed inta.e, but ha.n＇t significa.t effect on FCR. Consequently we concluded tha., using 2% CRP a.d different levels of SHRP ha. significa.t effect on perform.0}ce a.d ca.ca.s cha.a.teristics of broilers.

采用搅拌过滤法对a.hda.eh金矿样品进行金的萃提。矿物学研究表明,样品中58%的金颗粒小于10μm.该等级的3%属于难熔金。实验结果表明,在最优条件下,金回收率可达91.8%,银和汞分别为41.5%和10.2%。以氰化法测试的6种分次尺寸样品的结果表明,未萃取的金粒子大多小于25μm.还有大约5%的金颗粒大于25μm.因此,对样品要进一步粉碎,这样可使金和银回收率分别提高约3.57%和约5%,进一步粉碎样品并不影响汞的回收率。采用Knelson重力选矿法可提高汞回收率并防止金和汞的混合,利用氰化法检测重力法的尾料。这些方法的结合应用,最终使金回收率达到93.3%,汞回收率增加到42.16%,而银回收率没有明显的变化,为42.17%。
