Character of the deposit

Character of the deposit (eg) 509 Characteristic infrared absorption bands ... [Pg.859]

In this respect filterability behavior is apparently related to the character of the deposits formed. The more crystalline the deposit the less tendency to plug filters... [Pg.520]

There exists a large field of salt in Worcestershire, of which the principal bod lies throe hundred feet below the surface of-the ground but the rock itself is not worked, and owing to a deficiency of borings, the geological characters of the deposit have not been so thoroughly -studied as is the cose with the Cheshire field. The whole of the salt prepared in the county is made by the evaporation of strong brines. [Pg.899]

Tin-mining methods depend on the character of the deposit. Primary deposits are embedded in undeiground granitic rock and recovery methods are complex. The more important secondary deposits are in the form of an alluvial mud in the stream beds and placers and the recovery is simpler than lode mining. Cassiterite is recovered from alluvial deposits by dredging, hydraulicking where a head of water permits it, jets and gravel pumps on level... [Pg.56]

If the study is on a residual product, it should be noted that the character of the deposit will change with lime. Some insects are flushed out onto the wet... [Pg.189]

Current density is defined as current in amperes per unit area of the electrode. It is a very important variable in electroplating operations. It affects the character of the deposit and its distribution. [Pg.841]

The character of the deposition of y-(methacryloxy)-propyl-trimethoxysilane (MPS) on the surface of clay and calcium carbonate was studied. While most of MPS resists tetrahydrofuran washing when deposited on clay, MPS is removed by THF from calcium carbonate. Physico-sorbed layers can be removed by a solvent, whereas chemisorbed layers cannot be. Calcium carbonate does not contain hydroxyl groups (only some are available in admixtures), unlike clay which has a surface composed of Si-OH and Al-OH functionalities capable of covalent bond formation with silanol. Clay retains 66% of the silane applied, whereas only 19% of silane remained on the surface of calcium carbonate. [Pg.321]

Early last century copper was mined there on a considerable scale, and about 1845 the miners found a lode in which small lumps of peculiar yellow metal were imbedded. When it was tested this proved to be gold, but attempts to work the mine further for gold failed owing to the very patchy character of the deposits. [Pg.121]

Tassopoulos et al [1989] admit that these concepts are perhaps a first step towards a clearer understanding of the effect of system variables on the character of the deposit. [Pg.77]

The potential effect of deposit age on the qualities of the deposit, where the character of the deposit may change with time or thickness. For instance the changing temperature on the outside of deposits in a high temperature system (combustion) is more than likely to result in differences of porosity for example, within the deposit. [Pg.77]

As an alternative to direct heat transfer measurements it is possible to use changes in pressure drop brought about by the presence of the deposit. The pressure drop is increased for a given flow rate by virtue of the reduced flow area in the fouled condition and the rough character of the deposit. The shape of the curve relating pressure drop with time will in general, follow an asymptotic shape so that the time to reach the asymptotic fouling resistance may be determined. The method is often combined with the direct measurement of thickness of the deposit layer. [Pg.496]

In this paper, to meet the different requirements in self-healing CMCs, typical boron carbide and boron doped carbon was prepared by CVD ftom BCla-CH -Ha-Ar and BClj-CaH -Ha-Ar mixture, respectively. Microstructures, phases and chemical bonding characters of the deposits were systematically analyzed and the relationship between microstmctures and compositions was discussed. [Pg.49]

Metasomatic limestone is one where the original character of the deposit has been modified by the intrusion of secondary impurities. [Pg.415]

SEM and SPM were used to study the structure of copper films grown onto porous silicon (PS) by chemical corrosive deposition from copper sulfate and hydrofluoric acid aqueous solutions. It was defined that Cu deposits on PS in a form of nanosized grainy and porous films. Distributive character of the deposited Cu and the factors that influence the film structure are described. [Pg.479]

Inferred coal resources Coal in unexplored extensions of the d onstrated resources for which estimates of the quality and size are based on geologic evidence and projection quantitative estimates are based largely on broad knowledge of the geologic character of the deposit and for which there are few, if any, samples or measurements—the estimates are based on an assumed continuity or repletion of which there is geologic evidence this evidence may include comparison with deposits of similar type bodies that are completely concealed may be included if there is specific geologic evidence of their presence the points of observation are 1 1/2-6 miles apart. [Pg.793]
