In copper production (SX-EW), leaching, electrowinning and other energy-intensive extraction processes can be tapped for vast amounts of heat. Heat that can be fed right back into the flow, with an unparalleled yield. Compact heat exchangers – whether gasketed, welded or spiral – are the most efficient technology for heat transfer known to man.

Spiral round lock-seam duct is the most efficient way to transport air in HVAC systems. The round profile greater flow efficiencies than rectangular ducts. Because round ducts are inherently stronger than rectangular profiles, they can be lighter metal gauges and can be installed in longer spans. ... Leadership Extraction Practices ...

copper mesh that requires no secondary optical lamination to make it optically clear. This option offers a sheet resistance of 0.2 [Ω/sq] and a typical visible transmission of 76% (with one AR layer) or 80% (laminated between two AR layers) for 30 µm mesh width x 300 µm pitch. Refer to Table 1 for a comparison chart of transparent conductive ...

We present copper structures composed of multilayer, stacked inductors (MLSIs) with tens of micro-Henry inductance for use in low frequency (sub 100 MHz), power converter technology. Unique to this work is the introduction of single-level lithography over the traditional two-level approach to create each inductor layer. The result is a simplified fabrication process …

Our spiral separators for heavy minerals, including iron ore, chrome, mineral sands and other high-density minerals, separate particles in the size range 1.5 to 0.04 mm. We have 3-turn, 5-turn and 8-turn spirals with high-, medium- and low-gradient profiles. Our high-capacity spiral separator (the HX series) provides a per-start tonnage rating ...

As expected, the copper spirals performed better than the plastic ones due to the higher thermal conductivity of the copper. It should be noted, however, that the contact (heat exchange) area between the tube and the soil was 7.0 cm 2 /cm for copper and 10.5 cm 2 /cm for plastic, i.e. 1.5:1.0 ratio in favor of plastic tube. The linear length of the tubes per meter of the …
