Can has advice on "simplest" way to filter 7hydroxy mit?

I am by no means involved with chemistry in the slightest but I can follow directions decently and that's what I'm doing with making oxidizing mitragynine myself into 7hydroxy. I bought a setup that came with the guys sop on how he does it and I've managed to end up with a mixture of 7hydroxy, mitragynine, whatever secondary alkaloids I don't care about(citrate salts of these things) and the saturated baking soda water I used to neutralize the citric acid water I ended the process with. It was all dissolved in ethyl acetate then I acidified that ethyl acetate with 100ml/10g of citric then added like 50ml/5g baking soda water mix to get to the end. What would the simplest and most affordable route be to get the 7oh/mit to end up by themselves? His guide says silica 60 but nothing about what size column I need or if I need to add more EA to get it to flow through the silica? Thanks
