Rare earth tailing (RET) was obtained from a rare earth mining area in Western Sichuan Province, PR China. The main mineral phases in RET are phlogopite, collinsite, fluorite, and veatchite, according to the XRD result (Fig. S1).The chemical composition of the RET is of high complexity which contains a large amount of various rare earth elements like Sr, Ce, etc. …

Mill Tailings Sampling Method

Mill Tailings Sampling Method Our approach is to let the variability in the samples dictate how many samples should be collected and analyzed, and then to quantify and defend the results by means of standard statistical methods.

SAMPLING METHODS FOR IMPOUNDED TAILINGS

sampling. It is the most accurate method of sampling a tailing deposit, but it is usually too expensive to use. This method is used chiefly to confirm the results of auger sampling. Auger drills used for sampling tailing deposits are similar to wood augers. They obtain a sample by boring a vertical hole to the desired depth and on being withdrawn

Barium Samples

The number of electrons in each of barium's shells is [2, 8, 18, 18, 8, 2] and its electron configuration is [Xe] 6s 2. Barium is a member of the alkaline-earth metals. The barium atom has a radius of 222 pm and a Van der Waals radius of 268 pm. Barium was discovered by Carl Wilhelm Scheele in 1772 and first isolated by Humphry Davy in 1808.

Tuning the structural, optical, and dielectric …

The pure barium titanate sample, in the present work, agrees with ICDD Card No. 00-075-0212. The experimental unit cell volume of the pure barium titanate sample, which was found as 64.67 Å 3, is a little smaller than …

To explore the correlation between early strength and pore structure of cemented tailing backfill sample, cemented tailing backfill (CTB) with different binders and sulphate concentrations were made and uniaxial compressive strength (UCS) tests, mercury instrusion porosimetry (MIP) tests were performed on all samples at curing time of 28 days.The relationship between early …

Guidelines for Canadian Drinking Water Quality: Guideline Technical

Total barium in a water sample includes both its dissolved and particulate forms. Analysis of total barium is needed for comparison to the MAC. ... When the regenerant doses were increased from 4.0 to 6.0 and to 8.0 eq CaCl 2 /L resins, a barium concentration of 1.0 mg/L was achieved for run lengths of 500, 900 and 1,100 BVs, respectively.

The Evolution of LC Troubleshooting: Strategies for Improving Peak Tailing

Why Do We Care About Tailing Peaks? As is shown qualitatively in Figure 1, and quantified using the measure of plate number (N), tailing peaks observed in a chromatogram that is populated with at least some normal peaks will generally be broader than their symmetrical counterparts, particularly toward the base of the peak.This is not desirable for two major reasons.
