Agricultural blend and process of forming an agricultural blend
View Patent ↗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.
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.
