A method comprises providing feed petroleum coke particles comprising particles larger than a predetermined threshold size, particles smaller than the threshold size, and optionally petroleum coke microproppant particles, where the predetermined threshold size is greater than 105 μm, and sieving the particles to obtain a first fraction of petroleum coke particles and a second fraction of petroleum coke particles, where at least 75 vol % of the first fraction has particle sizes no smaller than the predetermined threshold size, and substantially all of the second fraction has particle sizes no larger than the threshold particle size, and the second fraction comprises no more than 25 vol % of petroleum coke microproppant particles having sizes no greater than 74 μm. The method comprises size-classifying the second fraction to obtain a petroleum coke proppant particle fraction comprising no more than 10 vol % of petroleum coke microproppant particles having sizes no greater than 74 μm.
