浮选

The integer part, the optional decimal point and the optional fraction part form the significant part of the floating literal.

整数部分，可选的小数点，以及可选的小数部分组成浮点文字量的有效部分。

A floating literal consists of an integer part, a decimal point, a fraction part, an e or E, an optionally signed integer exponent, and an optional type suffix.

浮点文字量由整数部分，小数点，小数部分，e或 E，可选的有符号整数指数，以及可选的类型后缀组成。

When this hydroxamate-xanthate collectorsystem used to float another highly siliceous pelitic copper oxide ore,a copperconcentrate of 25% Cu can be obtained with recovery of 85% for free copper oxide.

自由氧化铜回收率≥85%，选择合适的调整剂及相应的流程结构更有利于羟肟酸-黄药&混合剂&在Cu-Fe共生难选养化矿浮选中发挥最佳效用，不仅可以得到品位达36%的优质铜精矿。

Depending on the cleaning compound chosen, the oil can be either emulsified or split to the surface.

根据所选的清洗剂，油脂能够被乳化或者通过分层浮在表面。

The ore of arsenopyrite is very easy to float, but hard to inhibit, the experiment creatively forward to the "Select I" in the middling re-election, and then incorporated into the final railings discharge, re-election of concentrate back to roughing of the closed-circuit process. Succeeded in separation the iron of marmites and arsenopyrite the concentrate grade obtained Zn 41.56%, recovery rate is 93.08%, comprehensive collect silver, gallium, indium and other rare metals.

毒砂可浮性很好，易浮难抑，本试验创造性地提出了精选I的中矿再选、再选尾矿并入最终尾矿排放、再选精矿返回粗选的新闭路流程，成功地实现了铁闪锌矿与毒砂的有效分离，获得了锌精矿品位41.56％、回收率93.08％的指标，同时综合回收了银、镓和铟等稀贵金属。

Flotation tests were conducted with pure minerals and all sorts of different structral Organic depressants.

通过单矿物浮选试验从各种具有不同结构的有机抑制剂中进行性能筛选。

The technology of water washing can remove all above-mentioned harmful impurities except of P〓O〓 in crystal lattice. However, the feasibility of water washing technology may rely on the ability in investment as the initially required investment size is big. Also, this technology may cause a secondary pollution as the process generates large amount of waste water. Organic matters can be removed by a floating technology. Lime may be used as a neutralizing agent which transforms watersoluble P〓O〓, F〓 into salts of low solubility. Grinding can improve the crystal morphology and the gradings of PG. A combined technology of neutralization with grinding may have the advantages of both.

水洗可除去除共晶P〓O〓以外的所有杂质，但存在一次性投资大、工艺复杂、污水排放造成二次污染等问题；浮选可除去磷石膏中的有机物；石灰中和使有害态的可溶磷、氟转化为惰性的难溶盐；适当的球磨可有效改善磷石膏的颗粒形貌与级配；筛分可除去有害杂质含量特别高的部分，提高磷石膏品质；球磨与石灰中和结合的预处理工艺，既消除了主要有害杂质的影响，又改善了磷石膏颗粒结构与级配。

Microsilica silica fume and micro-production processes is the difference from natural quartz silica (SiO2) or fused silica (natural quartz at high temperature melting, after cooling the amorphous SiO2) by crushing, ball milling , flotation, acid purification, high purity water treatment by multi-channel processing of the powder.

硅微粉与微硅粉的生产流程上的差异硅微粉是由天然石英（SiO2）或熔融石英（天然石英经高温熔融、冷却后的非晶态SiO2）经破碎、球磨、浮选、酸洗提纯、高纯水处理等多道工艺加工而成的微粉。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
