Calculating Cyanide Consumption
Computing Cyanide Consumption of a laboratory leach test may be done as in the following example: Ore taken, 250 grams. Ratio of solution to ore, 3:1 = 750 cc: 250 grams. Cyanide strength, 0.3% KCN. Or when working on the metric system, Ore taken 200 grams, ratio of solution to ore 3:1 = 600 cc: 200 grams, cyanide strength 0.3% KCN

A comprehensive review of lithium extraction: From historical
In this table, we can observe that a standard spodumene ore sample contains a lower concentration of Li 2 O, specifically 2.14 wt%. This percentage is a crucial indicator, signalling that the ore is categorized as low-grade (Zelikman et al., 1864) (see Table 2). ... Spodumene is a mineral that is an important source of lithium, which is a ...

The following notes of a typical test will illustrate the method of calculating the consumption of cyanide and lime: Ore—400 grams. Lime added—0.94 gram hydrated lime = 0.65 gram CaO. Solution—1000 cc (950 cc H2O, 50 cc 1.0 per cent NaCN solution). Solution strength to be maintained at about 0.05 per cent NaCN and 0.025 per cent CaO.

pH Sensor for High Lime Concentration Slurry
One solution is to add lime via a timer system (20 seconds on, 20 seconds off) with the on/off ratio coupled to the slurry flowrate (i.e. controlling at a kg/t lime addition assuming the ore mineralogy and process chemistry does not change too much in a short time) and keeping an eye on the downstream pH.
