Abstract

The present disclosure describes an agricultural blend and a process of forming an agricultural blend. The agricultural blend includes a slag by-product from a process having a slag other than stainless steel slag or includes 11 atomic % silicon from a soluble compound and total silicon of less than about 30 atomic % silicon or greater than about 39 atomic % silicon. The process includes producing a slag by-product and blending the slag by-product with a liquid binder system to form the agricultural blend, the slag not being stainless steel slag.

Claims (33)

1. An agricultural blend, comprising:

a slag by-product, the slag by-product including a soluble compound having silicon; and

a binder system;

wherein the slag by-product in the agricultural blend is from a process having a slag other than stainless steel slag;

wherein the agricultural blend includes greater than 10 atomic % silicon from the soluble compound.

2. The agricultural blend of claim 1 , wherein the slag other than stainless steel slag is selected from the group consisting of carbon steel slag, aluminum slag, phosphate slag, copper slag, zinc slag, non-ferrous slag, argon oxygen decarburization slag, alloy steel slag, blast furnace slag, blast oxygen furnace slag, coal slag, and combinations thereof.

3. The agricultural blend of claim 1 , wherein the agricultural blend is agglomerated.

4. The agricultural blend of claim 1 , wherein the agricultural blend is pelletized.

5. The agricultural blend of claim 1 , further comprising a sulfate source.

6. The agricultural blend of claim 1 , further comprising a micronutrient packet.

7. The agricultural blend of claim 1 , wherein the soluble compound includes monosilic acid.

8. The agricultural blend of claim 1 , wherein the soluble compound includes polysilic acid.

9. The agricultural blend of claim 1 , wherein the soluble compound includes an organosilicon.

10. The agricultural blend of claim 1 , wherein the soluble compound includes calcium silicate.

11. The agricultural blend of claim 1 , wherein the soluble compound includes calcium inosilicate.

12. An agricultural blend, comprising:

a slag-byproduct having a soluble compound and an insoluble compound; and

a binder system;

wherein the agricultural blend includes greater than 10 atomic % silicon from the soluble compound; and

wherein the agricultural blend includes total silicon of less than about 30 atomic % silicon or greater than about 39 atomic % silicon.

13. The agricultural blend of claim 12 , wherein the soluble compound and the insoluble compound are a by-product from a non-metal slag.

14. The agricultural blend of claim 12 , wherein the soluble compound and the insoluble compound are a by-product from a metal slag.

15. The agricultural blend of claim 12 , further comprising a sulfate source.

16. The agricultural blend of claim 12 , wherein the soluble compound includes monosilic acid.

17. The agricultural blend of claim 12 , wherein the soluble compound includes polysilic acid.

18. The agricultural blend of claim 12 , wherein the soluble compound includes calcium silicate.

19. The agricultural blend of claim 12 , wherein the soluble compound includes calcium inosilicate.

20. A process of forming an agricultural blend, the process comprising:

producing a slag;

producing a slag by-product from the slag, the slag by-product including a soluble compound having silicon; and

blending the slag by-product with a liquid binder system to form the agricultural blend;

wherein the slag is not stainless steel slag;

wherein the agricultural blend includes greater than 10 atomic % silicon from the soluble compound.
