In contrast, methyl trialkyl ammonium chloride (Aliquat 336) exhibited high extraction rates across different organic to aqueous ratios (O:A) alone. Synergistic effects of MIBK, DEC, and TBP with Aliquat 336 were also evaluated, achieving 90.6% gold extraction at a 1:1 O:A ratio with reduced consumption of Aliquat 336. The McCabe-Thiele curve was plotted for the optimal combination, Alq336/MIBK/kerosene, revealing that three extraction stages were required at a 1:2 O:A ratio for optimal results. A batch counter-current simulation was designed, showing that the three-stage extraction process at a 1:3 O:A ratio increased gold recovery from 87.2% (using Aliquat 336 alone) to 93.3% with the Alq336/MIBK mixture. Stripping of the loaded organic phase was conducted with a 4 M sodium thiosulfate solution, achieving an efficient 98% stripping of gold from the organic solvent.

The results indicate that, as the V-N content increases, both the yield strength and tensile strength of the tested rebars are increased, but the strength–yield (Rm/Rel) ratio decreases significantly. This reduction in the Rm/Rel ratio for 88 V steel, and the Rm/Rel ratio falling below 1.25 for 140 V steel, can be attributed to factors such as the lesser impact of fine grain strengthening on enhancing tensile strength compared to yield strength, and the inability to continuously refine the ferrite grains in high-strength seismic rebars with substantial increases in V-N content. The proportion of large precipitates increases with the V-N content, and the relatively low precipitation rate in V-containing steel implies that the increment in precipitation strengthening is not linearly related to the V-N addition.
