Methods for treating and processing refractory gold ores are well established. However, what is less well understood is how the formation of the gold-bearing deposits affects gold processing and extraction. In order to evaluate the effect of ore genesis on gold extraction a number of South African gold deposits were studied.

The continuous elution process is a continuous counter-current system operating in a pressure vessel at elevated pressure and temperature in which both carbon and the eluate are simultaneously moving through each other in opposite directions. During this process the carbon particles enter the top of the vessel loaded with gold and exit …
As such, we need $mathbf{40}$ bits of the Gold sequence to determine the coefficients of this degree-$20$ polynomial, not the $21$ noted in cbos's answer. We don't get the two LFSRs shown in Dan …

Yindongpo is the largest known gold deposit in the North Qinling terrane (Zhang et al. 2013; Chao et al. 2023; Li et al. 2023a).It is hosted in felsic metavolcanic rocks with interbedded metasedimentary rocks (Zhang et al. 2013).Jiang et al. reported a sericite 40 Ar/ 39 Ar age of 374 ± 3 Ma, but subsequent sericite K–Ar and 40 Ar/ 39 Ar dating yielded much …
Gold codes Before describing Gold codes it is useful to define maximum length sequences. Linear feedback shift registers (LFSR) (Moon and Stirling, 2000) are called state machines, whose components and functions are: the shift register - shifts the bit pattern and registers the output bit; and ; the feedback function - computes the input bit …
The result of modulating an RF carrier with such a code sequence is to produce a direct-sequence-modulated spread spectrum with ((sin x)/x) 2 frequency spectrum, centered at the carrier frequency. The main lobe of this spectrum (null to null) has a bandwidth twice the clock rate of the modulating code, and the sidelobes have null-to-null ...

Gold Code. Gold code, also known as Gold sequence, is a type of binary sequence, use in telecommunication (CDMA) and satellite navigation (GPS). Gold codes are named after Robert Gold. Gold codes have bounded small cross-correlations within a set, which is useful when multiple devices are broadcasting in the same frequency range.

Of all the methods of extracting gold & processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation, cyanidation and gravity concentration. Tests that mirror each of these unit operations were utilized to evaluate the principal flowsheets. This …

By combining two of these sequences, we can obtain up to 31 plus the two m-sequences themselves, generate 33 sequences. I do understand why there are 31 ($2^5 - 1$) sequence length for a single m-sequence, but I am not sure why there are $2^5 + 1$ for the gold sequence.

A Gold sequence z is obtained by the binary addition of a "preferred pair" of m-sequences x and y [16] : z(k)= x(k)⊕y(k) (1) We will first review the main properties of m-sequences and then explain the meaning of "preferred pair". A m-sequence is generated with a Linear Feedback Shift Register (LFSR) sequence generator.
A Pseudo-random noise (PRN) sequence ia a closer approximation to white random noise in that its energy is spread equally over the occupied frequency band (The energy is spread as a Sinc function if reconstructed with pulses just because of the pulse shape but the underlying code as a stream of impulses has a more uniform distribution), …
Gold Sequences. Gold sequences have been proposed by Gold in 1967 and 1968. These are constructed by EXOR-ing two m -sequences of the same length with each other. Thus, for a Gold sequence of length m = 2 l -1, one uses two LFSR, each of length 2 l -1. If the LSFRs are chosen appropriately, Gold sequences have better cross-correlation ...
sequences to "top it off" to the desired length. To create a truncated ZC sequence of arbitrary length is also simple. Just create a ZC sequence of length N zc ≥ N sf and cut off the last N zc−N sf values of the sequence. In practice, cyclically extended sequences tend to be preferred to truncated sequences for reasons that are not ...

Their method of mining was then, and is now, the following: A small water-furrow is first brought in at the highest possible level on a suitable hill-side, and the stream is turned down the hill. By means of a heavy long wooden crowbar, shod with a long strongly- made chisel-pointed iron socket, and with the help of ...
