Abstract This article demonstrates possible separation of Pd(II), Pt(IV), and Rh(III) ions from chloride solutions by solvent extraction in rotating coiled columns (RCC). The most common reagents used for extraction of platinum metals were selected as extractants: trioctylamine (TOA), methyltrialkylammonium chloride (MTAA), tributyl phosphate (TBP), and relatively new …

Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).The device consists of a tower, around which is wound a sluice, from which slots or channels are placed in the base of the sluice to ...

A method and apparatus for performing switching by multistage interconnection of switching elements with improved performance and low layout complexity is disclosed. The techniques of line grouping, concentrators, self-route control through sorting are applied to relieve the output contention problem and uneven incoming traffic. Further a new class of interconnection networks called the divide ...

There are a number of design considerations which influence the selection of a suitable pitch and trough shape for a new spiral separator. The separation requirements impose certain constraints on the total design envelope and mutual interaction between some of the requirements and the conflict between metallurgy and materials handling requirements often defines a narrow range of …

Evaluate Spiral Concentrator Circuit Performance. Circuit analysis can be used to evaluate the overall effectiveness of various configurations of unit operations in mineral and coal processing circuits. This powerful tool, has regretfully seen only limited application in the analysis of coal processing circuits.

Spiral Concentrators (Flowing Film) Separation by density occurs as a result of primary flow and circulating secondary flow patterns that are created as the feed slurry travels along an elongated helical trough surface that spirals downward around a central axis.

Ore tailings at the terminus of a spiral concentrator are first split by a novel splitter box into value-rich and value-poor streams determined by the distribution of values therein, and the value-rich stream is upgraded, preferably by passing it through a conical gravity separator.

Testing was conducted to evaluate the performance of a multistage Multotec SX7 spiral concentrator treating ultrafine bituminous coal. This spiral mimics a two-stage separation in that the refuse is removed after four turns, and the clean coal and middlings are repulped (without water addition) and then separated in the final three turns.

Continuous Concentrators in Primary Gravity Circuit. Within the primary gravity concentration circuit, spirals and shaking tables are utilized for coarse liberated tin recovery. The tailings from the spiral and tabling circuit are reground to a P80 of 130 µm and processed through two Falcon C-2000 concentrators operating in parallel.

3.2-2 Different two-phase flow schemes are created in the boiling zone, including slug flow, where a slug of liquor is followed by a slug of vapor, similar to the perking in a coffee percolator; annular flow, where a ring of liquor encases a center core of vapor and liquid mist; and mist flow, where vapor blankets the tube surface. Mist flow conditions should be avoided because poor heat

The low chromium-to-iron ratio of chromite ores is an important issue in some chromite deposits. The value of the chromite ore is indeed dictated in the market by its iron, as well as its chromium content. In the present study, a chromite concentrate was reprocessed by gravity (spiral concentrator) and magnetic separation to enhance the chromium-to-iron ratio.

In this study, modeling of spiral concentrator for concentrating the ultra-fine chromite was investigated. A three-level Box–Behnken design combining with a response surface methodology (RSM) and quadratic programming (QP) were employed for modeling and optimization of spiral concentrator performance.

Different spiral concentrator profiles. Spiral usually operates at 40-50% solids and the design can consider employing a hydrocyclone as the first separation stage. In this way the underflow can be directed to the spiral. Once the slurry is in the spiral, light and heavy mineral are classified according to their densities.

Industrial extraction of mineral resources would be inconceivable without extremely efficient treatment technologies. Whether in wet or dry separation, production plants are exposed to unimaginable flow rates and wear potentials.Often set up in the most inaccessible places in the world, our industrial well-being depends on the "smooth" function of these machines and plants.
