1999-2-1  The function of limestone is to provide alkalinity to the batch reactors. Without limestone, pH decreased by 3 to 4 pH units to less than 3.5, and 4 to 5 times more sulfate was produced than with limestone, depending on the pH decrease and how the reactor was run. Based on Fig. 1, the S:L ratio of 3:1 was chosen as the optimum S:L ratio. Lower

2012-8-31  Limestone is a chemical sedimentary rock that is created from the remains of calcium bearing organisms and chemical precipitants. The calcium can come from the shells and/or the skeletal fragments of deceased organisms. Over millions of years, the calcium normally contained within the shells of marine and land organisms is broken down and put into solution. Calcium rich solutions are

Limestone an overview ScienceDirect Topics

Open limestone channels (OLCs) are constructed to direct AMD flows within a channel that has been lined with limestone. An OLC is very much like an ALD without a cap. An OLC is an oxygenated environment, so the Fe present in the AMD can “armor,” or coat, the limestone present in the channel.
