FTIR, XPS, and ab initio molecular dynamics studies demonstrated that sodium silicate (Na2SiO3) adsorbs on fluorite with a higher affinity when they are treated beforehand by sodium carbonate (Na2CO3) due to proton exchange(s).

The ore from Jingping contains 0.634% nickel, 0.329% copper, 0.047% cobalt, 30.18% SiO2and 19.72% MgO. In order to obtain satisfying beneficiation results, a lot of tests were taken out before, and this article main focus on roughing flotation conditions. Finally find that when the sodium carbonate dosage is 2000g/t, carboxy-methyl cellulose (CMC) dosage is 200g/t, sodium silicate dosage is 100g/t, the combinational effect can depressing the gangue minerals as well as the slime. The final concentration contains 3.03% nickel, 2.01% copper and 2.40% cobalt, the recovery of the nickel, copper and cobalt is 73.03%, 92.58%, 77.62% respectively.

In this study, according to the characteristics of scheelite in run-of-mine, the scheelite was concentrated by adopting the full flotation process with sodium carbonate as regulator agent, sodium silicate as inhibitor for gangue minerals, lead nitrate as activator and ZL pharmacy as collector. 6.15% of the coarse scheelite concentration with tungsten recovery of 96.18% was obtained from the raw ores with grade of 0.86%. The concentration of rough tungsten by heating, by which the high-quality scheelite with tungsten of 62.31% and tungsten concentrate recovery of 93.53% was obtained.

Mineral Salts are One of the Most important Non-Metallic Chemicals that were widely available in ancient Iraq, and due to its many Uses in life Matters and for industrial purposes, it was Allocated in the Study of a Type of these Salts, which is Sodium Chloride salt (Table Salt), as there were Several Types, including: - Calcium Sulfate Sodium Silicate, Sodium Carbonate and Potassium Nitrate Because of the Importance of Sodium Chloride (salt) in Ancient Iraq and the lack of Studies that Dealt with it, we Chose it as a Subject for our Study, and we Relied on Many Arab, Translated and Foreign Sources, the most important of which are: -Levy, Martin, 1980 , Chemistry and Chemical Technology, translated by: Al-Mayahi and others, Dar Al-Rashid. - Potts ,D.,1987,'' ON Salt and salting gathering in Ancient Mesopotamia ''(JESHO), vol.27‎.
