of primary-only variable flow chilled water pumping systems com-pared to the conventional primary-secondary pumping system. One article1 even predicts the fidemisefl of primary-secondary systems. While there is no question that the primary-only system has many ad-vantages, the primary-secondary system may still be preferable for some ...
Mining and Processing. Pyhäsalmi uses non-entry, bulk open-stope mining methods in a primary-secondary sequence. On average, stope size varies from 50,000 tonnes for narrow primary stopes to over 100,000 tonnes for wider secondary stopes. Milling includes crushing, 3-stage grinding, conventional flotation using three separate circuits, and water removal to produce copper, zinc and .
A system of primary and secondary stopes is often used in VCR mining, where primary stopes are mined in the first stage and then backfilled with cemented fill to provide wall support for the blasting of successive stopes. Side chambers will be mined in pre-planned sequence after the fill has solidified. Block mining methods
Cluster mining tools; Tools for mining secondary metabolite biosynthesis gene clusters ... (BGCs) that encode duplicates of primary metabolism enzymes, but display a divergent phylogeny. This is based on an observation that such primary metabolic isoezymes are often included in secondary .
What comes after primary, secondary, tertiary? The sequence continues with quaternary, quinary, senary, septenary, octonary, nonary, and denary, although most of these terms are rarely used. There's no word relating to the number eleven but there is one that relates to the number twelve: duodenary.

Primary-Secondary-Tertiary Pumping. In a primary-secondary-tertiary system (Figure 3), things start to get a bit more complicated, but the principles are all the same. The common pipe (whether it is between the primary loop and the secondary loop, or the secondary loop and the tertiary loop) acts as the decoupler, so flows act independently of one another and there is extra degree of thermal ...

The first way in which proposed mining projects differ is the proposed method of moving or excavating the overburden. What follows are brief descriptions of the most common methods. 1.1.3.1 Open-pit mining Open-pit mining is a type of strip mining in which .
Primary & Secondary Belt Cleaners Fenner Dunlop manufactures high quality belt cleaners for a host of different applications. Our heavy duty design best serves the mining (surface and underground) and aggregate industries.
The term "secondary crushing" has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed.
Kanowna Belle gold mine in Kalgoorlie. Figure 10 shows the stoping sequence for a mining block where the extraction sequence was based upon a primary stope extraction and filling with consolidated fill, before the secondary pillars were extracted. The numbers on the figure refer to the stope extraction sequence.
Primary Mining Method Sequential grid down dip. Information. To deal with ground pressures, a V-shaped mining sequence is utilized. The main advantages of the sequential down dip method are the very low energy release rates, which make backfilling unnecessary, and the allowance for the physical separation of rock transport from men and materials.

Primary and Secondary "1-5-9" (or "1-4-7") Stope Sequence. By still using the general triangular retreat shape of a pillarless sequence but instead using an arrangement of small lift primary and secondary stopes, a compromise can be made. This increases the productivity by making multiple primary stopes available for mining simultaneously.
