The primary loop uses a constant speed pump to circulate the working fluid. Also, what is a secondary loop? “P” is the primary pump, which will run continuously. “S” is the secondary pump. When the secondary pump is off, no water will flow through its loop because the DP of the secondary loop is greater than the DP between the tees.

In nearly four decades of practice as a geologist it suddenly occurs to me that I can''t supply a rigorous definition of primary vs. secondary minerals, so I too would be interested in a definitive answer. For now, though, one comment: I have never heard the term "secondary" defined in terms of any particular process, e.g. oxidation-hydroxylation-hydration reactions within the weathering zone

Studies of remagnetization mechanisms are discussed, and we summarize methods to discriminate between primary and secondary remanences carried by hematite in natural samples to aid primary remanence extraction in partially remagnetized red beds.

Hematite ( / ˈhiːməˌtaɪt, ˈhɛmə -/ ), also spelled as haematite, is a common iron oxide compound with the formula, Fe 2 O 3 and is widely found in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe. 2O. 3.

We present a novel technique for quantitative unmixing of primary and secondary ferrimagnetic minerals in sediments. Hysteresis and high-resolution first-order reversal curve (FORC) measurements are performed on sediment samples before and after digestion in a citrate–bicarbonate–dithionite (CBD) solution optimized for maximum selective extraction of secondary fine-grained iron oxides.

In some mine tailings, primary sulfides have been completely dissolved and replaced by secondary minerals such as hematite. It seems that formation of hematite is very fast under tropical climate conditions with distinct rainy and dry periods typical for countries such as Zambia and Namibia. Immobilization of contaminants in hematite has implications for other mining sites around the world
