Extraction of edible red pigmengt from solanum nigrum fruit by optimum seeked process conditions, determined single factor condition, designed orthogonal layout, and measured absorbance at 527nm wavelength, weighed up the pigment extracting effect and stability. The most favoured extracte conditions were determined as follows: The extracting regent was citric acid hydrotropic solution, pH was 1.72, the quantities of added sample to the solution was 3.35g/100mL, the temperature was 60℃, the extracting time w...

以成熟的龙葵果为原料提取食用红色素，通过优化工艺、确定单因素条件、设计正交试验，以527nm波长的吸光度值衡量色素提取效果和稳定性；最优化的提取条件为：柠檬酸水溶液提取剂pH为1.72，样品加量3.35g/100mL，提取温度60℃，浸提时间60min；龙葵红色素提取液长期接触光、空气和Fe3+，稳定性下降，因此，在提取、干燥和储存时要尽量避免长时间接触光和空气、避免与铁制容器直接接触。

The effects of three collectors,benzyl arsionic acid,diphosphonic acid and C_(79) alkyl hydroximic acid,on ilmenorutile,fersmit and niobite floatation with the various pH and collector dosage are investigated.

研究三种捕收剂在不同pH和用量的条件下对纯铌铁金红石、铌钙矿和铌铁矿的捕收影响。

Phosphonic acids, hydroximic acids, arsenic acids and cationic not only have a strong collecting ability, but also have a strong collecting selectivity which is better than that of fatty acids.

认为脂肪酸类捕收剂的捕收能力较强而选择性较差，与钽铌矿物作用时生成了铁和锰的油酸盐，而不是钽铌的油酸盐。

Effects of several collectors on pure ilmenorutile were studied and compared in this paper.

The electrochemistry and the mechanism of jamesonite, marmatite with collectors have not been reported and the study blazes new trails.

脆硫锑铅矿、铁闪锌矿的电化学及其与捕收剂相互作用的机理未见有报道，具有创新性。

With butyl xanthate as a collecter, the flotation behavior of jamesonite, pyrrhotite and marmatite, the depressing effects of small mercapto organic depressant (mercaptoacetic acid, mercaptoethanol ) and the effect of Cu2+ ion on depressing ability of mercapto compound were studied through flotation test and infrared spectrum.

摘 要：通过浮选实验、红外光谱测定，考察了脆硫锑铅矿、磁黄铁矿和铁闪锌矿在丁黄药作用下的浮选行为和巯基类小分子有机抑制剂对三种矿物的抑制效果以及Cu2+离子对巯基化合物抑制效果的影响。

Experiment about flotation characteristics of amesonite, marmatite and pyrrhppite are done. According to the result, we can select suitable collection and reagents to inhibit iron minerals .for the separation of lead Zinc minerals Small-scale experiments of flotation separation of lead and antimony minerals .

采集了脆硫锑铅矿、铁闪锌矿、磁黄铁矿等纯矿样，进行了这些纯矿物的一系列浮选性能试验，并以纯矿物的试验初步筛选铅锌浮选分离的组合捕收剂、硫化铁矿的抑制剂。

Using butyl-xanthate as collector, marmatite can be activated by Cu2+ with the presence of glyceryl-xanthate and then possesses good floatability,while pyrite can't be activated,therewith these two minerals can be separated.

结果表明，用丁黄药作捕收剂，在甘油基黄原酸钠存在下铁闪锌矿能被Cu2+活化从而具有良好的可浮性，而黄铁矿不能被Cu2+活化，从而实现两种矿物的选择性分离。
