    In a method of froth flotation of minerals from carbonaceous ores in the presence of a collecting reagent, a step which comprises adding calcium lignin sulphonate to a pulp of the ore, and subjecting the pulp to froth flotation in the presence of said lignin sulphonate and in the presence of the carbonaceous matter. 4.Limestone for pH Adjustment in Industrial Wastewater,Limestone is an alkaline agent with the ability to neutralize, or partially neutralize strong acids. The neutralization process occurs when strong acids, in intimate contact with limestone chips, react with Calcium Carbonate (CaCO 3, the primary constituent of limestone) to form water, carbon dioxide, and calcium salts. The following depicts
